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.

worth the price abd then some Review by thx1138 / (Posted on 5/30/2019)
I am very happy with the performance of this light. I have it in the veg tent and its caused a huge surge in growth when compare to my previous light (a 240 watt HLG 4000K light with all white diodes).
Excellent Light and value for money Review by Hairyman@afn growauto@instagram / (Posted on 5/14/2019)
I have been very impressed with this light , replaced 450watts of blurple with excellent results.

Suitable for germing, veg and flower .

Great light distribution and spectrum.

Great build quality and like they say easy to hang, its a plug and play light.

Fell in love in 3 days with first one and now have 4 with 4 more just ordered. Review by MG (Midnight Gardener) / (Posted on 4/25/2019)
Ordered one of the SP 250 to try out and in 3 days I noticed sizable gains compared to my reflectors so ordered 3 more to fill a 4x8 tent and the results blew my mind. Actual full coverage of the tent , spectrum is great but would like to be able to mount drivers outside of tent for even better temperature control. I just ordered 4 more for my other 4x8 tent and will now reap the benefits of increased productivity at lower wall wattage than using now. Sending me a “gift” even though I was late for the 420 sale.
Excellent quality light at a great price Review by Lars / (Posted on 3/20/2019)
I'm really pleased with the quality of these lights. They are an excellent replacement for HPS/MH lights. I measured the evenness of the illumination using a quantum light meter, and it's far better than a HID light. The build quality of these things is excellent, it's full spectrum, so easy on the eyes, and water resistant. They are also so much lighter than HIDs and easier to hang and move around. I'm now thinking about purchasing several more for the university where I work.

I wish you could still get them at the preorder price, but even at the higher price, they are still a bargain for this quality light. Kind of crazy to think that just a few years ago you would have to spend nearly a thousand dollars for an LED light that would be lower quality than this one. Nice job Mars Hydro.
Unreal light for the price point. On off would be nice Review by Polish Pride Grower / (Posted on 3/14/2019)
At around $1 a watt 2 bars light a 4x4 like a airport runway. Sunglasses are a must when working around the lights. I could easily see 2 grams per watt 9 plants in 3 gallon pots in a 4x4 under 2 sp 250s. Mars should offer a option with a 12 foot cord with the option to have the driver outside the tent so no wiring modifications need to be made. Excellent Choice
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
Exciting Review by Cheffrey / (Posted on 1/29/2019)
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.
good light Review by Luke Watson / (Posted on 1/4/2019)
My SP200 looks very good and I hope it gives me good results
Great Product! Review by Smith P / (Posted on 1/4/2019)
I'm glad you can give me a 10% discount for my preorder. I'M LOOKING FORWARD TO IT!
