New Grower Recommended LED for 120cm x 80cm x180cm ( 2x auto blueberry)

[anonimus]

Hello!

Which led light is recommended for my tend (120cm x 80cm x 180cm) , i wanna have two plants in this tent, if its possible? ( 2x Blueberry dutch passion ).

And another question is, if i need to change in between bloom and grow or i can have both on , because the plants are autoflowers?

Greetings!

My basic grow mantra is one mass built led light with no more than two plants. Now that I have dumped my mass built led lights and changed to cob lights, I use one cob for one plant (currently testing two lights per one plant. I'm doing two of those). They have reflectors as well. www.cobshop.net is where I bought my cobs. I got th 3500K which is good for the entire grow. You can get ready to hang like my 3500K or partly complete, that you finish. I've had my cobs for several grows now and I still like them immensely. My cobs are small and easily moved, highly efficient, low electrical draw, no noise, low heat and my plants have been healthier. Check them out.

You can find nutes for just about any situation. You can get something like nutes that are parts A&B and just use that for the whole grow or get many nutes to micro nute manage. It really comes down to what your lifestyle will allow.

Maybe i will have one problem... This tent will be in a cold room and if a fresh air from outside comes in then i need a light that produce enough heat to have around 23-28*C in tent.

You can always add heat. I use a radiator style heater (I feel it is best heat) that I put inside an old two drawer file cabinet and push that up to one of the tent lower window type openings bottom of tent. The inline fan sucks in the heat and all is well.

I am sure plenty of people have grown 2 plants under a Mars II 400. As I mentioned earlier, 2 plants was my max under one mass built led light. Cobs aren't quite in the mainstream just yet, but are getting there pretty damn quickly. I have been highly impressed with their performance. Certainly it rests heavily on your budget.

Mars is ok for a while- but theyre made with cheap diodes and drivers and routinely fail after the first 2-3 grows. Not bashing them they will grow decent plants but you get what you pay for- i just bought a mars 700 to get me through a couple grows!

Cobs from the likes of cobsshop.net are made with top quality meanwell drivers passive heatsinks (no fans that might eventually fail) and citizen cobs.
2 cobs-3 max would do awesome in that space.
But as autowonders mentioned it also comes down to budget

Thank you for answers!

Yes i Will first time have ingrow in tent. So for the start my budged its not high, max 200€ , later i Will buy better light... But for my first start im looking for my tent a best choice light for 2 plants , just to get started and get decent grow from the light when i buy it.

Maybe i Will buy just one cob light from the link above . How much real Watt use this cob ?

I decide to buy 2x Almost complete CoB light 3500k and buy separately drive. I just wanna know if i buy ( MEAN WELL HLG-60H-C700A 700mA ) if i cant wire up this two lights with this driver with no problem? Driver output is 100V so the cob is 36v x 2 = 72v , but both Will then run on 50v ( 100v/2 = 50v) , its that ok?
