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 21~38 actual watts of power per square foot for TS series grow light.

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: 30'' 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 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.

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.

Recently purchased this light, love it very much, plants grow obviously. The only issue is the panel gets hot, cannot touch it, is this normal? Should I do something?

The TS 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. 

Rate the answer?
Is the panel waterproof?

TS is not water proof, please make sure to clean the light now and then in order to ensure its longer lifespane. 

Rate the answer?
I received the light, but the whole panel cannot turn on? What is wrong?

Hi TS has two connection side, one is for the power cord, another side you need to plug in to the panel aka pcb board. Please check if you have plug in both sides. If both sides is connected, the light shuold be on. If both sides is connected and the light is still not turn on, please email us for warranty:

My panel arrives, but the shape is a little changed, help!

The TS series is all aluminum for heat releasing purpose. But at the same time, the alunimnum is soft and easy to change shape during shipping. So the panel might change a little shape when you get it. But they will also be easy to use a hammer or something to return back shape as well. We are also keep improving our package to avoid more of these happen. Hope you can kindly understand. 

Rate the answer?
Can the TS be daisy chained?

Hi, TS cannot be daisy chained 

Rate the answer?
Is just one TSW 2000 light suffice for a 4x4 tent?

Hi one of the TSW 2000 is suitable for 4x4 during veg, but if you use the light during flowering, it will be only suitable for 3x3 area. You can try two of the SP 250 or TSL 2000 if you are looking for lights for 4x4 for whole cycle. 

Rate the answer?
What is the dimmable wattage range, how low can I get?

Hi Sir, you can get from 25% of the light to 100% of the light wattage, which is around 75w the lowest. :) You can use a screw driver to adjust the wattage on the driver accordingly. :)  

Rate the answer?
Do I need to buy any other equipment for the light to work? Can I just plug it all in and install it in my tent?

Hi all of Mars Hydro lights are plug and play design, you don't need to buy other ballast or reflector to make it work. :) 

Rate the answer?

Great product Review by James / (Posted on 8/16/2019)
I love this new light the plants have been responding very very well to it, the only thing I suggest it to have a fan blow on the driver a little bit throughout the day as it gets hot from the light being on 12 hours minimum a day
