You should have added the 2 400w hps I would have chosen that. having a 400w mh in flower will make smaller buds. Its nice to have the blue spectrum in flower but not that much. try the 430 sonagro they work nicely for me.What would grow the best biggest buds for a 3x4 room, 1 600W HPS or 2 400W (dual spectrum) side by side for 3x4 room! thanks!
Oh yeah. I didnt see that part. I wouldnt put a MH in a flower room either.You should have added the 2 400w hps I would have chosen that. having a 400w mh in flower will make smaller buds. Its nice to have the blue spectrum in flower but not that much. try the 430 sonagro they work nicely for me.
I do know that lumens do start to cancel themselves out at a certain amount but I don't know exactly the formula for that. I do know that this doesnt apply to you though. With your space and having 2x 400 watt will be perfect. If you had something like 4x 400 watt than I would maybe start to think you have an overload of lumens.ok now I have another question, at which point are the lumens cancelling themselves out? like say you have to 400 W side by side, part of the plants get exactly the same amount of each light ,... can you say it doubles in lumens?
I have 2 ufos as side lighting, if I put my hands in front of the HID, I cannot see the red or the blues from either LEDs, is this light still doing it`s job?
now say you have 4 400W side by side forming a small square, can you say you have the same lumens as a single 1600W bulb?
The message you have entered is too short. Please lengthen your message to at least 10 characters.so do I keep both 400 running through flower or a 600W hps would be a good investment, or a 400W conversion bulb an even better idea?
