Please, I really need some opinions and suggestions about my new light.
I have a new 3x3 grow tent, since my old 2x2 was really worn-out.
I used mainly a 250w mh/hps but it's not enough to cover a 3x3.
My main choices are these two:
- Mars Hydro II PRO Epistar 120 600w: it looks like a good led light, anyway I'm not sure if it's enough to cover the tent. Not really sure about the noise and the fact it doesn't produce heat: sometimes the heat it's helpful to manage temperatures.
- Lumatek CMH 315w kit with a 3100k bulb for the full run [I do a short vegetative stage, or at least I can use the 250w MH for the veg].
It's noiseless and perfect for a 3x3 tent.
Anyway I can't understand if you can run it ay 25/50/75% of the power without damaging the bulb and if the closed reflector needs an air extraction like for the cool tubes.
I'm not considering HPS/MH anyome because I don't want to consume 400w or more.
ANY considerations or suggestions will be very very helpful!
thank you guys
