How can I distribute light evenly to my plants across a 10x10x8 area

hey guys Im trying to use a 400w horilux Mh light to veg plants in a pretty large area. basically I have 10 plants at the moment but they are all seeds so im just planning for the future. They are regulars so lets say I end up with ~5 plants to spread the light across. I want to grow these plants as big as possible within my space. I will add much more lights including cfl's and led's in the future.

I am only using this space for veg growth never flowering, and plants will be removed once they reach the desired size.

What do you want to know?

Train them, look up LST, rotate your plants every other day so they get even lighting

So you want to grow 5 plants in a 10x10x8 with a 400W... Iol. 5 plants in 3x3 a under that 400 would work much better. You'll need a minimum of 4 1000s to get good coverage over a 10x10x8.

Generaly accepted light coverage
400w= 3x3
600w=4×4
1000w=5×5

the 400watt is just a start, And do you know how many watts of cob leds I would need for 10x10?

To much, that's dumb. Have you ever grown weed before?

want the most out of your light surround it with plants
if you want the most out of your plants surround them with lights.

Minimum, I would say. A lot of people aim for 40-50 watts/foot of good quality cob lighting. I use 32 X 50 watt cobs for my 9X5 bloom area and get great results and yields, but could most likely benefit from a couple more 4X50 watt frames

I'm running 900 watts of Citizen/Cree in a 4x8, and I'm averaging 2.5 lbs every time. I used to get the same weight off of a pair of 600s.

Yeah I have gotten 1650 and 1725 grams my last 2 run but I feel like with a little more perimeter lighting and experience (I definitely have A LOT to learn still ) I could hit 2000 grams. I only have 20 months experience with the first 4 lost entirely due to... issues caused solely by me, myself, and I :/

One cheap thing you can do is to get a handful of those mirrors found on the back of (often bedroom) doors. I see them like 18 x 48 inches and they are great for leaning up against the wall in your grow room. Kick them out so the bottom on the floor is 6 inches or so from the wall. That'll help shoot the reflected light back up into the plant. I've found a good place to find the mirrors is at your larger thrift stores.

Good luck, BigSteve.

Don't listen to Big Steve. Mirrors absorb light. You're better off sticking to flat white paint.
