As more and more led manufacturers start to sell white led, I think white led will led led future, Gavita, UnitFarm grow bar, mars hydro bar, Fluence...said withe led can save 30% electricity

Day 33 UPDATE #16 DAY 35 The plants had almost emptied the 225 liter Flexi tank. Was in doubt whether or not to induce flowering. Decided to let them grow another week, so I filled 100 liters, put in 1/2 recommended dose of Canna A & B, pH'ed the water to 5,8 and opened the tank. Guessing the...

If you visit Mars Hydro website , you will see their new light: white grow bar, very bight, I heard they need testers. If you are interested in, I advise you to send them email

DAY 27 When I opened the door to the grow-room today I was kinda shocked. Not only from the massive smell from it, but also from the massive growth that has happened since the last time I went in to check on them. All plants are looking fabulous. No problems whatsoever. I finally managed to...

The design of Timer lights are very different from most of led light in the market, thank yo , I will google more information about it

Thank you brother, Fluence is good light, but my budget is very limited for their lights, maybe I prefer a Chinese brand or UnitFarm grow bar, they are more affordable

Your growing picture looks great, may I know what brand led white light you used?

I just bought a led glasses to protect my eyes and help me see plants clearly, I will update the growth of my plants soon.

Maybe you can try their new light, I saw they have white grow bar now, 600W can replace 1000W hps, I did not test it, so I don't know if it is true, but the pictures seem great

This year white led light seems popular such as QB, Gavita led, Mars Hydro white grow bar , may I know if any of you use this white light? How about its efficiency? Most white light suppliers said 600W led can replace 1000W hps, is it true? I shared the following picture I saw with you.

When I entered the room today temperature was 30 degrees and humidity 85%. During the night the intake-fan had died and there was no fresh air coming into the room (except the passive air sucked in by the under-pressure created by the exhaust-fan). Luckily I had one spare fan, so I replaced it...

Sara at MarsHydro told me they will have new product in Market 1--2 months later, I think it is time for you to contact them to test their new light if you had complete grow journal before.

I think traditional led is not too efficient compared with HPS/HID...for example, if you want to get the same yield as 1000W HPS, you still need 900--1000W led , right? This year white led is more popular, I heard this led is more efficient than traditional led, but I did not try it, not very...

Thank you, I have contacted with Mars, I told them I am writing a grow journal with their light to share my growing experience. They are very happy and said they will send me one glasses as gift.

Nothing new to report, but took a photo of one of the Pure power plants to show how they are progressing. Looking quite good. Could also see the two I separated is still growing. However a little slower than their sisters

I can not see plant clearly when I turned on my Mars lights, should I buy one led glasses to solve this problem? I am a little short-sighted, so I am worried usual led glasses can not help me a lot.

I am growing 10plant, ProII80 led is too small to work for my plants Lol, I won one MarsproII1600 led during Mars Cup competition 2years ago, I am very happy with it after I tested it, then I bought another 2 pcs.

It will not take lots of electricity bill, because the draw power of their light is very low. I think its King led' advertising strategy to attract traffic.

Draw power of 1500W king led is only 260W, they said they use 10W chips, so draw power of each chip is only 1.73W. My MarsproII1600led uses 320pcs of 5W chips, draw power of light is 750W, draw power of each 5w chip is 2.34W, so I think King led is misleading customers by exaggerated watt of...
