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.Recommended Lighting Time

Veg: 18/6(on/off) or 20/4(on/off) Flower: 12/12(on/off)

5.Recommended Growing Conditions

The rate of photosynthesis and transpiration is 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.

6.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.

What is the difference between SP200 and SP 250? They look the same.

Hi, the SP 200 is the original name of SP 250, all the specificaiton is the same. But our factory made a mistake to put the original stickers and instruction book when we ship the first several shipment, so some of you might get the light with wrong item number and specification data on the sheets. please refer to the current site info for reference. 

Rate the answer?
Recently purchased the SP250 and love it, but the power supply gets too hot, is this normal?

The SP series are no fan design, so the panel needs to release heat itself. We are using all aluminum meterial for the light body, and all the material are anti-fire, over 90% of the components are UL listed, so the light won't catch fire. Also the heat is under control, won't influence the lifespan of the light. Please don't worry. BTW, the whole room temperature won't increase too much. If you don't like the heat of the light, you can add one small fan above the light, it will help a lot, also during winter, it will not be a problem as well.

Works great then it shut off Review by smallgrow / (Posted on 3/20/2020)
Love the light but 3 months into my grow and it just turned off. I don't know what the problem is but a few mins later it came back on. Now I'm wondering if I need to buy a new light to replace this one. Up to now it's been a great light. I hope I can find out what the problem is with the light and get it fixed or my plants will suffer.

Hi Smallgrow, our lights have 1 year total free and 3 years limited warranty, please kindly email us at: solutions@mars-hydro.com and we will help you solve this issue. :)
Great light! Worth the $ Review by madmike / (Posted on 3/8/2020)
The light runs very cool especially with drive out of grow area. The is really bright! It’s so far producing nice looking buds! Hands down for the price you can’t beat this light.
10/10 would recommend! Review by Sean / (Posted on 2/27/2020)
I have one SP250 I received in January for my. Medical grow, I have ran 3 plants flowering at 12/12 since I got it and they are doing amazing.
I threw one of my trichocereus cacti in there and it seems to be loving it as well after sitting in my window sill for months. I am going to buy another one now and possibly more soon for my indoor vegetables and succulents.
It is a very well built light, I bought this after deciding I wanted more power than my blurple reflector from them.
Totally recommend over the cheaper built ones or the way over priced gavitas.
Only concern is with quality of hanging hardware and one hole that makes the light hang uneven Review by RedbeR / (Posted on 2/27/2020)
After much reading of grow journals and product reviews I decided to pick up 2 of the SP 250.

Shipping was fast and packaging was of good quality and fairly discrete in nature!

Customer service has been prompt and courteous when a question arose about a possible missing product on my door step. (Neighbor picked the boxes up since it was raining and forgot to tell me)
Set up was easy.

My criticism is small at this point and is directed toward the hanging of the light and the gear provided.

The gear is of lighter duty then I am comfortable with. The plastic parts on the rope ratchets the rope itself and the metal hooks are thinner then most I have purchased or been provided for the HID Reflector kits that are 1-2 times lighter then the weight of the SP 250. Also one of the hanging holes on one side of the light does not go all the way through the metal and blocks the hook on the metal hanger so it does not hook all the way through the hole. This does not make me feel comfortable using the metal hooks AND the light does not hang level.
Best lights for money value. Excellent service. Review by Georgios / (Posted on 1/27/2020)
I just purchased 2X SP-250 and 4X TS100w lights.They have been delivered fast and in perfect condition. I would also thank you for the amazing gift. The lights look to be excellent after the first measurements taken before the setup. A second review will be followed regarding the efficiency of the lights during the grow. Thaks Mars Hydro and hope to deal again.
Outstanding Review by Madlib / (Posted on 12/18/2019)
Best light I’ve owned so far. Excited to see what the future has in store.
Very happy so far Review by Dye82 / (Posted on 12/2/2019)
Got 2 SP250 for my 120x120x200 grow box.
Extremely fast shipping and nice customer support.
The light is very well built, you can detach the driver from the led bar and put it outside your grow box, thanks to the long cable, so you'll have less heat and humidity when the light goes off.
Plants seem to react very well to the light, they're only 3 days in veg so I'm keeping the bars at about 70-90 cm distance.
I will update my review after the harvest but I'm very happy so far.
I love this light buying 2 more Review by Kindbuds2019 / (Posted on 11/29/2019)
I just bought a 250 and love it. Very well built bright full spectrum light you can't ask for more for the money.
Very impressed Review by Shotgun Facelift / (Posted on 10/12/2019)
I just purchased a sp250 for my 2x4 tent. I replaced a 300w and a 600w blurple and I am very impressed so far. The switch is in week 3 of flower so it will be interesting to see the results.

So far I am very impressed with the light. Not only is it nice not having the purple glow, but has balanced my number beautifully. I am currently not having to run AC, and just plumb in some cool fresh air from an open window through a carbon filter.

Over all, so far, very happy and glad I purchased the SP250.
