Grow Tips

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.

Buy one, seriously, you'll be impressed Review by GoldGrower, check me out on Grasscity and Instagram / (Posted on 3/10/2019)
I've been using the Mars SP-250 for a few weeks now and I'm super impressed with it. Compared to my HPS set on 250w it's twice as bright. It's lightweight, bright as hell, cool running, silent running, the light is a crisp white showing all the colours of your plants beautifully and your neighbours won't be suspicious from the standard purple light that so many LEDs have these days if you accidentally shine it through your curtains or something.

Being splash proof means you can wipe over the diodes with a damp cloth when they become dusty, this is so underrated in my opinion. Pretty much all the heat comes from the driver which is above the light so under it stays very cool, and if you wanted to you can take the driver off and positioned it outside the grow area by fitting an extension cord. This would reduce the heat even more but I find mine so cool it isn't necessary.

I like my reviews to be balanced to I want to say a couple of negative things but I honestly can't think of any. I haven't had any problems at all. Oh ok here is one thing I would change, it doesn't have an on/off switch, one of those would be an improvement, but it's a very small problem. And a dimmer which is easily accessible and adjusted without tools would be good. You can actually adjust the wattage /brightness but you need to unscrew the driver first which isn't ideal. That covers everything I guess. Buy it, you won't regret it

Just order 3 for my 4x4 tent. Cant wait!
Excellent Value! Review by Steve in MN / (Posted on 1/25/2019)
A very high output light at a really good price. I doubt you could find a cheaper light with this much output. The 4000K is a very visually appealing color temperature. Mine is drawing 257W@AC120V. I did dedicate a small fan to blow on this light since the driver gets pretty hot. I may see if there's a DC cord extension so I can mount the driver outside my tent. I noticed that some of the LED's appeared to not be on, but they were all in the same pattern on the strips, so I'm assuming that these are emitting infrared light. I wouldn't think twice about buying this light again.
