Your plant internode spacing looks great toaster, do you use the same cabinet for flowering? So i should aim for 150-200w lmc561 for flowering?
Thank you all for helping a newb.
Oh, forgot to mention. Just built this one and those two plants weren't raised in there. For now I'm keepimg pepper seedlings in there beside those two canna plants and am strugling somewhat. Need to mount the dimmer and attenuate lights some.
I'm thinking of doing a sog run in there. Start 24 seeds, cull males and see how it goes. Probably 12/12 from seed.
You should look at 25-30W/sqr' if using qbs or cobs. And like I said, a single cob, even if it can handle 150-200W, would make for a crappy coverage. Probably bleach/burn your plants in the middle with that footprint.
