How many plants under 4ft 8 bulb T5

I just purchased a sunleaves 8bulb T5 system. The bulbs are 54w a piece. The grow room is 4x2.5x5. I planned on 8 black cream autos. Can anyone help me on this one

at least 3 thousand

Itll work but the yield will suck. Good Luck

If your flowering with t5 you are gonna want all the plants pretty much directly under the light and the light 6-8 inches off the top of the plants. You'll do best if you build a screen slightly wider than the size if your light and scrog them plants. T5s have good output but crap penetration. You have to have a real even, short canopy if your flowering with them.

I like to have 10 auto's in 1 gal pots
With 8 I would go with larger pots.
I also have 4 ft 4 bulb for side light

How many plants can I fit under 4 8 bulb 4ft t5 in 3 gal smart pot

One very wide but not too tall plant.

Currently doing 4 plants under a 8 bulb 4 ft t5 ho light, adding some leds in flower, currently in veg. This is my 5 t5 grow and once you get it down the results will speak for themselves. Be sure to use the right bulbs in flower most t5 fixtures onky come with blue 6500k veg bulbs. You want 3000k to 2700k bulbs in flower. Imo a scrog with 2 larger plants or 4 smaller plants may be the way to go when using t5 to flower. If i contiune to use t5 i may do it next grow with clones from my current bag seed plants.
