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.

Fantastic light for the money. Review by Joegoods / (Posted on 4/21/2019)
Fantastic light, works great. I highly recommend the Mars pro 2 cree 256. This light is great for the price and the customer service was very helpful during my communication before I purchased it. I did a lot of research before I purchased this light and it's a great buy for the money.
Maybe too powerful. Review by Lunchbox / (Posted on 1/15/2019)
This light is VERY powerful! Keep high above the canopy when bloom is switched on since it can easily 'light burn' your plants.

Not recommended for anything less than a 6' tall tent.
Wow Review by James / (Posted on 12/5/2018)
Fantastic light. Have used for 3 grows in a 4x4 tent and have been blown away by the increase in yields. Much bigger buds in density. Increased my temps by 10 degrees so not bad at all. It is super quiet for fan noise. It is pricey but a grow light is not what you want to scrimp on when setting up a grow room. Well worth it! You won't be disappointed. Am currently looking at the 300w for a second grow.
Awesome Review by MuShMaNn / (Posted on 11/27/2018)
Awesome light, throughly impressed with the quality of this product. Plus as everyone else has stated about this light, my girls love it and it shows!!!!
Top Notch! Couldn't be happier! Review by Fredrik / (Posted on 11/11/2018)
This light is amazing! I had a 400w from the reflector series and this Pro model is of the charts! I have harvested a lot of veggies since I got this instead. Worth the price and fast delivery too!

Great light. Much better grow than with the HID light. Very good seller A+ Review by James / (Posted on 7/13/2018)
Great light. Much better grow than with the HID light. Adds about 10 degrees to your temp so make sure you have good ventilation.
Amazing light your plants will love! Review by Jam Bo / (Posted on 5/17/2018)
Amazing light, runs really cool and outputs so much light it's crazy and the plants love it!
Big Improvement Review by ThaGreenBandit / (Posted on 5/22/2017)
Upgrades from the Mars 400, and the difference was obvious. Definitely a worthwhile investment
Great light. Much lower heat and denser flowers Review by Dustin / (Posted on 3/8/2017)
Great light. Runs much cooler than comparable HID light. Plants grow just as fast. Much more dense thick sticky flowers. So dense in my instance that I almost doubled my yields. Very expensive, but well worth the price if you factor in yields and electricity costs.
