Hey there
@Burr_nit -- all the best for your plans.
If you talk to
@MarshydroTina she'll look after you fine!
I have a Reflector 192 (~400W) in a Mars 120x120 (4'x4') tent.
It's doing very nicely with some herbs. Check my signature line.
Most of the time that's just the veg mode, not flower mode.
That's 400W/16sqf = 24W/sqf, about bare minimum level.
For a 5'x5' tent, that's 25sqf, so you'd want between that,
and up to 40W/sqf. Figure from 600W to maybe 1000W.
The Refl 144 are rated at ~300W. So even 2 to 3 of them
in a 5'x5' grow would be about right.
Hope that helps you!
