Grow Tip

1.How do I determine the right light for my grow area?

Measure the floor space. Multiply the length times the width and this will give you the square footage. You should be able to get decent results with 30-50 actual watts of power per square foot.

2.For larger areas should I go with a single large panel or multiple medium to small lights?

Using multiple lights allows you to better distribute the intense light in more areas of the grow space instead of having all of the higher intensity light concentrated in only one area while the outer edges never receive intense light.

3.Recommended Hanging Distance Above Plants

Seedling: 24'' Germination: 24''-30'' Veg: 18''-24'' Flower: 12''-18''

4.Here are more tips for grow under our light:

Growth stage, turn Growth switch on. Bloom stage, turn Growth and Bloom switches on.

5.Recommended Lighting Time

Veg: 18/6(on/off) or 20/4(on/off) Flower: 12/12(on/off)

6.Recommended Growing Conditions

The rate of photosynthesis and transpiration are directly affected by temperature, humidity and airflow.

The perfect temperature and humidity for your plants are found between 75°-85°F and 50% - 70% humidity, with plenty of airflow to replenish CO2. PH is 6-6.5. You may add more calcium and magnesium than normally needed.

7.Please Note

The light is not water-proof, so do not use it under water environment.

Light may be too strong, please wear your sunglasses when looking at it.

Some leds seem dim. They are IR. Human eye can not see IR very clearly, but you can wear sunglasses to check.

I bought this light for my indoor vegetable garden, and I have been absolutely amazed with the results. My yields have been great! The system runs cool and fairly quite. I have not noticed much of a power consumption increase. You cannot go wrong for the money!

Great for some North American Pitcher Plants Review by Bill

I bought this wonderful light from Mars Hydro's Sean Shao because I grew carnivorous plants indoors. Parrot Pitcher Plants, Sarracenia purpurea venosa, and other S. purpureas thrive under it, but it's too bright for Venus Flytraps. It runs cool, the LEDs stay only warm to the touch, and to protect your retinas, you may need sunglasses to block the blue part of the spectrum. If you grow the plants I grew, this light is great for most of them.

I am more than happy to use your lamp! Plants growing very healthy and when it combined with hydroponics, it giving perfect results!
For anyone who is doubt about this lamp I want to say that I am not disappointed, Even after some diodes has burned out, I just wrote to support and they sent me new diodes and I replaced them. Its easy.

PERFECT FOR WHAT I GOT! They are perfect for 2x2x2.5 ggt! (I hope it's alright If I say that) easy to use case fans with tubberware & mesh screening for homeaide odor nuetralizer ( a "cf" u no)that in my idea is perfect for 3' ONES; sog; 6-9 indica flowers. Suprised me! thought i found a pearl! I would NOT STOP MARSII 400 AT LEAST FOR THE ONE like me. It's all I need to be successful. Just telling u. The da wants to surround me with concrete for one year, I think I'm gonna accept plea bargain for small amount.possession green? Yes! And giving rides but , all gravy; when I GET OUT IM GONNA NEED ANOTHER A FEW MORE AND GET ANOTHER 2x2x2.5 ggt! Pray and hope they will still have them available. Well done manufacturer of the one I bought. I understand trying to match the big star (sun) if you are but I see losing the mars II 400 for 2x2x2.5 ggt the same as losing my business. My #1-4-$. If they quit making this one looks like I will have to find someone else with same genetics as the mars II 400 0R BUILD MY OWN. Anyways, bummer, I got time to think about since I'm taking one years "behind no alcohol bars" maybe it will be like John the Baptist, or one of the Paul's, or the one grater than even these. Heavenly job to keep at least this particular one for what I got! But I do need another one year from now. My He! Will give me another when I walk out then in my whites! Thank you MARS-HYDRO! Reconsider for me or save me three more one year from NOW!
