Grow Tips

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 stage: 24~30‘’,Veg Stage: 16~24‘’,Flowering Stage: 12~16‘’

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.

Rate the answer?
I am considering purchasing a couple of Mars Pro II 1200w Cree 256 , but I would first like a detailed copy of your current warranty to examine first. Specifically, I want to know how long the warranty is, what it covers, and if it covers replacement of the light should it fail, and for how long that lasts. I am aware that Mars failed to honor their warranties properly in the past and that Mars was banned from THCFarmer for this specific reason, and I want to know if this problem has been fixed prior to even considering Mars.

This is the best lights I have owned. Review by littleob / (Posted on 2/4/2017)
I have 3000 watts of Mars Hydro LED lights and this one is the best of all of them. Mars Hydro just keep getting better with every upgrade. My latest harvest was very impressive for me. Flowers are bigger, denser and sticker than I have ever grown. I have never had a warranty issue with Mars Hydro, when needed parts were delivered in a timely manner and that means less down time for me. I recommend all of Mars Hydro products
