15.5 sqf area how many lumens required ?

Hi guys

Im starting a new tent for a autoflower grow.

This will be my first time at autos and want to dial everything in as much as possible.

The space i will be working with is a 1.2 x 1.2 x 2m tent so 15.5 sqf.

My question is ideally how many lumens per sqf would be ideal ?

I have 2 x 600 watt lamps free at the moment and also 2 x 250 watt lamps.

I plan on growing 8 autos in this space in DWC (might be a bit of a squeeze) in the space mentioned.

My plan is to SCROG the 8 plants and get my light as close as possible to the canopy but just cant work out how many lumens per sqf i will need to optimize my yield.

I have a fair few indoor grows under my belt all done in soil and all yielded an normal crop and dry weight ie 2-3 OZ per plant.

Any help with this area and what light combo that would be best to tun would be greatly appreciated

Cheers !

5000-10000 Lm sq/ft is a good zone to be but 5000 minimum for dense buds. Those 2 600s will do fine in there throwing out 11,613 Lm sq/ft which is more than optimal.

2-600 in a 4x4 IMO would be over kill. You're biggest limiting factor is you're canopy space.

the sun is about 10,000 lumens per sq ft so if you get close to that you're doing amazing, and with 2 600w you should be able to do that easy.

I'm guessing your tent is going to be a bit hot with 2 600s. I run 1 in a similar space while a 1000 might be optimal.
