Thanks for the responses. So if I have 4 hoods and 9 plants, wouldn’t the distribution be uneven to have 2 plants on each light then one with 3 plants? Also would two 450w led’s (400 true watts combined) work fine for the veg cycle? Thanks for the help.
No, imagine you are lighting the room, not the plants. Space the lights evenly so each covers a 4x4 then space the 9 plants evenly underneath. Imagine a tic tac toe grid, put a plant where the X's and O's go, then put a lamp where the lines intersect. I mean, it wont fit exactly like that, but you get the idea.
As for the LED, it will grow plants well for sure, but I still feel the plants could overgrow your veg space under that much light. But it's hard to say without trying it first.. I purposefully try to keep my plants small and manageable until I have the space to let them go.
Only one way to find out...
