Sun Systems

Technical Information Guide (Lights)

Important Product Information.



  1. Remove the system from the box along with all additional parts.
  2. The Smart Volt™ systems come standard with the 120 volt Smart Volt™ power cord. The Sun System® 1 and 6, Harvest Pro™ and Harvest Pro™ Elite have the Power Pointer™ voltage selector. The Sun System® 10 and Budget Gro™ have the Power Slider™ voltage selector. Make sure it is on the 120 volt option to plug in the provided cord. To change the voltage on the Sun System® 1 and 6, Harvest Pro™ & Harvest Pro™ Elite, simply pull out and twist 180º (Fig. 4a). For the Sun System® 10 & Budget Gro™, slide the door to the marked 240 volt side (Fig. 4b). To use the 240 volt you must purchase the 240 volt Smart Volt™ power cord (#903082 or #903084) separately.
  3. Switchable Units: When using a SS-6 MH/HPS (Metal Halide/High Pressure Sodium)
    switchable unit, switch the system to the MH side to run a Metal Halide lamp or HPS to run a High Pressure Sodium lamp. For a SS-6 1000 switchable, select the HPS option of the ballast by pushing the bottom of the switch so that the red part of the switch is visible. Press the top part of the switch for MH. A SS-6 400 switchable is marked HPS400 for the HPS side and MH400 for the MH side.
  4. Connect the socket to the hanging reflector (see reflector setup Fig.4). If the lamp cord is included with the reflector, skip this step.
  1. Now connect the lamp cord to the remote ballast (Fig.2). Make sure to attach the securing ears to the plug.
  2. Carefully screw the proper lamp into the socket. Refer to lamping instructions on the ballast.
  3. For SS-6 units make sure to select the proper setting on the ballast to match the lamp that is
    being used. Make sure the switch is properly set for either MH or HPS type lamp (Fig.3).
  4. Lastly, turn the system on by plugging the power cord into the proper NEMA configured receptacle.
  5. You should use a properly rated Smart Volt™ cord (120 or 240 volt) for the power that you are using. If you energize this ballast with 240 volt power while the female end of the power cord is plugged into the 120 volt receptacle you will “fry” the ballast and void the warranty. If you want to run this ballast with 240 volt power, you should purchase a 240 volt Smart Volt™ cord separately.

Proper Bulb Care

Bulbs should be replaced every year to maintain maximum lumen output. If a lamp fails to reach brightness, please contact your retail store.

Fluorescent Fixtures

If there are bulbs that will not fire, try swapping the bulbs around for others that are working. This will help determine if the bulbs are defective.

  1. See (Fig. 5) for attaching the socket on reflectors which do not include the socket.
  2. Some reflectors will come with a built-in socket assembly, while others you will need to purchase one separately.
  3. If the reflector does not have a built in socket, use a socket assembly that is sold separately. Choose from Product No. 903055 or 903060.
  4. Some reflectors include glass. For other reflectors it may be purchased separately if you choose to use it. Typically people use glass to control air movement through the reflector during air cooling. This also protects/contains the environment of your grow area. Glass is not required when using HPS lamps for the ETL listing to apply. It is required for MH lamps for this listing to apply. The glass installation process will vary by reflector type. It is, although, a very simple process for all Sun System reflectors.
  5. Use an eyebolt or some other means of hanging securely from the ceiling.
  6. V-Hangers (Fig. 6) are used to hang the reflector.
  7. SunLifts, #710125, Grow Yo-Yo, #710129 (Fig. 7) or jack chain may be used to adjust the hanging height.

(SUN SYSTEM® 2, 4 & Sun System 150)
  1. Remove the system from the box along with all additional parts.
  2. These systems do not require much setup. Carefully screw the proper lamp into the socket, refer to lamping instructions on ballast.
  3. Hang the fixture using the V-hangers provided.
  4. (On/off switch should be in the off position.) Plug the unit into the proper NEMA configured receptacle.
  5. Turn the fixture on using the on/off switch. Some systems may not include this feature.
enclosed system



  1. See reflector setup section for hanging instructions.
  2. Insert the self-ballasted compact fluorescent lamp.
  3. Do NOT screw the lamp in by holding onto the glass tubes, hold onto the plastic base to screw the lamp in.
  4. If the unit has on/off switches make sure these are in the off position before plugging the system into the outlet.



  1. Remove the system from the box along with all additional parts.
  2. Hang the unit using the eye bolts, V-hangers and jack chain provided (Optional cable hanger systems can be purchased separately).
  3. Insert lamps (refer to label on product for correct lamp) into the system. To do this, slide both ends of the lamp into the lamp holders and rotate the lamp 90º in either direction (Fig. 8a). For the Ready Fit® T5 unscrew the water proof protective plastic cover counter clockwise. The protective cover will have to go directly on to the lamp before inserting into the lamp holder (Fig. 8b). Insert lamp and rotate 90º in either direction and slide the water proof protective cover back on and tighten.
  4. Some New Wave® & Sun Blaze® models have the capability to be daisy chained together. Do not exceed 7.5 amps on any fixtures chained together. Do not daisy chain more fixtures together than what is specified on the fixture. Chaining more fixtures together than specified will void the warranty on all fixtures.

A general guideline for the proper hanging height of an H.I.D. lamp would be 12”- 48” depending on wattage (see below). Make sure to check for excessive heat at the top of your plants by placing your hand (palm down) over your plants. If the top of your hand is hot, you need to move your lamp up higher. If the light source is too close to your plants, you can burn them. Remember that as your plants grow you will need to adjust the height of your lamp.

Please keep in mind that the latest air-cooled reflectors, like the Super Sun® 2 allow you to place higher wattage bulbs closer to plants than was possible in the past.

When you raise the light up & away from your plants, you need to be aware that the light levels to your plants will be significantly reduced.

As light moves away from its source (the lamp) it diminishes as follows: 1/Distance2. For example: 1 ft. = 1000 FTC, 2 ft. = 250 FTC, 3 ft. = 111 FTC, 4 ft. = 63 FTC, 5 ft. = 40 FTC, & 6 ft. = 28 FTC (FTC = foot candle).


A fluorescent fixture can be placed much closer to plants than an H.I.D. fixture because it produces very little heat. You should place your fluorescent lights as close to the tops of your plants as you can without excluding the outside perimeter of your garden.


150/175 watts covers approximately 2’ x 2’ area

250 watts cover approximately 3’ x 3’ area

400 watts covers approximately 4’ x 4’ area

600 watts covers approximately 6.5’ x 6.5’ area

1000 watts covers approximately 8’ x 8’ area

NOTE: Coverage area may be reduced if this is your primary light source.

height adjustments for wattages


  1. CHECK YOUR ELECTRICAL SOURCE: Make sure the unit is plugged in properly and that the breaker is not tripped or fuse blown.
  2. CHECK THE LAMP: Make sure the lamp is screwed in all the way.
  3. FOR T5 FLUORESCENT FIXTURES: Check to ensure lamps are properly locked into place. This is accomplished by turning the lamps ¼ turn in either direction.
  4. Try a different lamp if you have one available. Make sure unit is unplugged when changing lamps.
  5. Make sure you have the correct lamp for your ballast, i.e. an HPS lamp will not ignite with a MH ballast.
  6. MVP™ (Multi Volt PowerCord): When using a MVP™ plug, only use the one distributed with the unit or purchased at one of our Authorized Retailers. DO NOT make any changes to the Power Cord. This will VOID the warranty.


Symptom: My ballast is humming but the light isn’t coming on.

Solution: There may be a couple of reasons for this: 1) the lamp is not screwed in tight enough, or 2) the lamp is defective. Please allow 5 - 10 minutes for lamps to initially ignite. If this does not solve the problem, return the unit to the dealer for testing.

Symptom:My ballast makes an excessive amount of noise.

Solution: Keep in mind that the higher the wattage, the louder the humming noise emitted. However, if the noise level is extreme, the transformer may have come loose. In this case, the ballast unit should be returned to Sunlight Supply®, Inc. for repair if it is still under warranty and has been used under normal operating conditions.

Symptom: Every time I turn on the light fixture, the circuit breaker trips.

Solution: You may have too many appliances on this circuit. A normal home’s circuit has only 15 amps available. These H.I.D. lights use up to 10 amps per unit. Please make sure you are not overloading the circuit with too many appliances and/or lights. Note: The sticker on the ballast will state the number of amps required by that particular unit. If you do require more lights/appliances to all be run off the same circuit, you should consult an licensed Electrician.

Symptom: I turned off my HID light and now it won’t come back on.

Solution:Your lamp may take up to 20 minutes to cool down before it can be fired up again. Fluorescent lamps should be almost immediate.

Symptom: My lamp has small pieces of glass inside of it.

Solution:It is common for small pieces of glass to break loose inside the lamps; this will not affect the lamps output. If there is a crack or hole in the outer glass, it should be replaced.


How do I know my lamps are functioning normally?


  • It may take HID or T5 fluorescent 10-15 minutes to come to full brightness.
  • HID: During the first few hours of use, the light from the lamp might oscillate.
  • HID: The light will decrease in intensity during the life of the lamp.
  • HID: During the first hours, intensity of the light may fluctuate somewhat, which is normal. However after it reaches 100 hours of “burn in” time, will continue evenly the remainder of it's life (with normal aging reduction).
  • Both: Average life of a MH (metal halide) lamp is 12,000 hours for a 1000 watt lamp and 20,000 hours for a 400 watt lamp. The rated hour life of a HPS lamp is 24,000 hours. Most users choose to replace lamps before they cease to operate due to lumen loss and spectral shift. T5 fluorescent lamps offer a rated hour life of 20,000 hours and have a much slower lumen loss and spectral shift than HID lamps.


On average, a light system will increase your electricity cost from $8 to $20 per month—the exact amount depends on the size of the system and the number of hours operated. However, since these grow lights are so energy efficient, you are getting huge amounts of light (and growing power) for your money! Make sure your grow room’s power circuit can handle the power draw. For safety reasons, do not exceed 75% of the rated ability of the fuse/ breaker (for example: use no more than 15 amps on a 20 amp circuit). To calculate your cost, multiply the bulb wattage X hours of operation and divide by 1000. This figure is the number of kilowatt hours of electricity consumed. (Example: a 400 watt bulb running for 18 hours will use 7.2 kilowatt hours). Check your power bill for the cost of each kilowatt hour. Then multiply the number of kilowatt hours by the cost of a kilowatt hour (K/hr) to arrive at the cost per month to run the light in your area.

Nutrient Calculator

Nutrient Calculator 

What does NPK mean?

NPK is a rating system that describes the amount of nitrogen, phosphorus, and potassium in a fertilizer.  The NPK nutrient values are expressed as a percentage of the total weight of the product in the package.  As an example, out Peace of Mind® Tomato & Vegetable fertilizer has an NPK of 7-4-5.

Nitrogen, represented by the first number, is responsible for leafy, green growth and is most important in a plant’s early growth stages.  Some plants, like tomatoes, are heavy nitrogen feeders and will quickly deplete the soil of nitrogen if more is not added.

Phosphorus, represented by the second number, supports root development, fruit and flowering, and helps the plant fight off disease.  It helps plants transfer energy from one part of the plant to another.

Potassium, represented by the third number, helps plants fight off disease and weather extreme heat or cold.  It regulates the synthesis of proteins and starches.

The NPK ratings of organic fertilisers tend to be lower, but that does not make them any less powerful.  There’s more to a good fertiliser than NPK.  The organic, biologically active nutrients we use in our organic products have a “functional value” that can’t be measured in a test tube.  Beneficial micro-organisms, pre-digested enzymes, vitamins and amino acids are the key to the power of an organic fertiliser like Big Bloom.

Our fertilisers may also include micro nutrients such as calcium and magnesium, trace minerals, and beneficial microbes that meet specific nutritional needs.

What is "pH"? and What is the ideal pH for my vegetables and flowers?

Soil pH measures the acidity or alkalinity of the soil.  A neutral soil that is neither acid nor alkaline has a pH of 7.  Acid soils are considered low pH (below 7) and alkaline soils are classified as high pH (above 7).  Some plants thrive in an acid or alkaline soil, but many common garden plants prefer a neutral soil.  If a plant is in a soil that is too acid or too alkaline for its particular needs, it will be unable to access the nutrients in the soil.  No matter how much you fertilise, the plant won’t thrive unless you adjust the soil’s pH to meet the needs of the plants. 

You can buy a simple home test kit to measure the pH of your soil, and then you can adjust the pH gradually.  Acid soils can be neutralised with calcium or agricultural lime, and alkaline soils can be corrected with sulphur or with regular applications of mulch or aged manure.  However, it’s important to make these adjustments gradually to avoid shocking the plants, and in general we encourage you to choose plants that naturally do well with your soil type.

Our fertilisers and soils are pH-adjusted to meet your plants’ needs.  For instance, our Peace of Mind® Fertiliser for acid-loving plants like rhododendrons and azaleas is pH-adjusted to meet the needs of flowering shrubs that prefer acid soils.

In general, hydroponic systems work well at a pH of 5.8 – 6.0, and garden soil will support a wide variety of plants with a pH of 6.6 – 6.8.

Why use earthworm castings, bat guano and humic acid in products? 

When we get enthusiastic about a particular ingredient, we can get a little carried away.  That’s why you’ll find three of our favourite ingredients – worm castings, bat guano, and humic acid – in so many of our products.

Earthworm castings are teeming with beneficial microbes that help plants thrive.  Scientists have tried to reproduce every nutrient worm castings contain in the laboratory, but they’ve been unable to create a formula that feeds plants as well as that rich, black, worm poop does.  Earthworms – and their castings – help roots access nutrients that are in the soil, and help plants fight off pests and diseases.

Our proprietary source of bat guano is naturally high in phosphorus, which helps create dazzling color, scent and taste.  It is also packed with beneficial microbes and helps fight off harmful nematode infestations.  Bat guano also helps facilitate the transformation of soil nutrients into a form that is easier for plants to absorb, making it the perfect catalyst for our fertilisers and soils.

Humic acid is a natural by-product of organic decomposition.  It contains trace amounts of nutrients and it helps hold other nutrients in the soil where plants can use them.  It can improve the humus content in the soil, hold water in the soil, and generally improve soil health for better seed germination and plant growth.

What’s MYCorrhizae?

Mycorrhizae is a word that describes a symbiotic relationship between a fungus and the roots of a plant.  Mycorrhizal fungi attach to plant roots and deliver water and nutrients to them.  Tiny strands, called hyphae, can stretch long distances in the soil in search of the nutrients a plant needs.  They promote root development, fight off disease, break down fertilisers, and they can even fight off harmful soil borne microbes and encourage the growth of beneficial microbes.

We include endomycorrhizae, which form on the insides of plant roots, and ectomycorrhizae, which attach to the outside of plant roots, to support a variety of plant life.  Under the microscope, mycorrhizae colonies form nodes that look like little rice crispies attached to the roots.  The entire surface area of these nodes can absorb and transmit nutrients.

What’s a bacillus? 

If you look at the ingredient listing on our products, you’ll see that we often put a powerful squadron of beneficial microorganisms in the mix.  What’s all the fuss about microorganisms?  Read on:

We also include Bacillus subtillus, a beneficial bacteria that controls the growth of a number of plant pathogens, including blight, scab, grey mold, and mildew.  It’s particularly useful for garden vegetables and fruit trees.  Adding a natural disease-fighter like B. subtillus to our products helps ensure that your plants will stay healthy, and it also improves the long-term health of your soil.  

Can I mix dry and wet fertilizers together? 

You can use our dry mix and liquid fertilizers in combination with each other.  However, we suggest that you mix dry fertilizers into the soil according to package directions, water well, and wait a few days before applying a liquid fertilizer. 

Can I mix FoxFarm fertilizers with products from other companies?

Yes, but for best results, we recommend that you Keep the Family Together.  Our products are designed to work together and complement one another.  If you are using a FoxFarm feeding schedule.  We strongly recommend that you not add another company’s products to the feeding schedule to avoid the possibility of a nutrient lock-out.

Is it possible to burn plants with FoxFarm fertilizers

Remember that American Pride® and Marine Cuisine® do include some organic ingredients, but they are not 100% organic fertilizers.  Two of our liquid fertilizers, Tiger Bloom® and Grow Big®, are also not 100% organic.  Our soluble products, like Open Sesame®, Beastie Bloomz® and Cha Ching®, also contain inorganic ingredients. If you use too much, you can burn your plants.  Remember when you use these extra strength, time release fertilizers, less is more.  

Don’t forget that a powerful plant food needs to be used as directed.  Be patient, because a little goes a long way.  American Pride® and Marine Cuisine® are meant to be mixed into the soil, so make sure you water thoroughly, pull excess fertilizer away from the base of the plant, and don’t allow fertilizer to sit on any external part of the plant. 

Also, a helpful hint when feeding: always make sure that you water first, so that the soil is moist, then feed.  This will help prevent possible burning with any fertilizer you use.
