Need Help! Best Choice for Fluorescents in a 4 x 2 box
Currently in the process of crafting a 4 x 2 box for vegetative growth of my plants. I cannot use an HID lights for this setup so I need to choose my best option for fluorescent tubes.
I already have 3 4ft T8 fixtures each with 2-32W Daylight (6500K) bulbs used on my previous grow with decent results.
I could use two of those (each 4ft long by 1ft wide) to have 4-32W T8 bulbs which puts me at 11,000 Lumens (1375 lu/sqft). I have read various different things about the amount of lumens needed per square foot so would these lights be sufficient for what I need them to do? Otherwise my only other option is going to HO T5's
Given my space I could go with a 4ft 8-Tube T5 setup giving me 40,000 lumens (5000 lu/sqft) but that would cost around $200.
The 4ft T8's I already own have seemed to do alright in my previous run, with about the same conditions. Is that adequate? Or would spending the $200 and increasing my lumens output be the way to go?
i would spend the money on the t5 you will be a lot better off than with the t8

Can anyone shed some light on the minimum, preferred, and optimal amount of lumens per sq ft would be in my situation?
