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: 20''~28‘’ Veg Stage: 16''~20‘’ ;Flowering Stage: 10''~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.

Love tech&nature Review by Fisherman / (Posted on 6/15/2019)
Highly recommend for one huge plant in a 1mx1mx2m tent, It consumes less electricity than reflector 1000W and gives less heat, (Caution if you're living in a studio type of apartment/house, would never recommend you to buy 1000W, (it heats so fast in summer!)) Go, low people, plants can't take more than they could. 300w is perfect for a single huge plant, 1kw is perfect for 4 plants in the 2m wide growing area.
Good luck Review by Nad / (Posted on 1/11/2019)
I used 2 marshydro two years ago and the results are amazing with dutch passion autos
The tent is 120*150*250
I started to 50 100 gamms per plant but the second year is amazing 3 400 gram the average yield any autos what i tried
1 plant 1 light is the best you can do with dwc technology only 10 20 minutes daily set up to 90 100 day and voila
So highly recommended

Best on the market Review by D / (Posted on 10/13/2017)
Mars lights are in my opinion the best on the market. The specifications of these lights are in the same range as your more expensive led's but at a very reasonable price. Don't be fooled. There are cheaper led's out there but not better. I had a spectacular harvest from this light. I'm very impressed with the results. Getting ready to purchase another one with a tent.

Great value Review by Frankir / (Posted on 3/12/2017)
Mars hydro led grow lights are very powerful lights as a reasonable price. My plants absolutely love these lights. I use my mas II 400 in a 2x2 grow tent. Mars hydro is the solutuon to your grow needs if your looking for high end led at a low cost.
