I bought 4 4ft T5 agromax UV bulbs, I am going to put 2 of them, one on each end of my 4 bulb veg lights. My question is will they be okay on young seedlings? About a foot away 24/0?

That is too much, you'll burn em. I run UV through out but I use a 15 watt led on seedlings that has 1 uv diode, I run 1 uv T5 in veg and 3 in flower

and ya want to start that UV bulb 36 inches off the canopy

a foot away, 24/0, = death for sure

Should I put the one in the center or the end in veg? In flower I was gonna alternate bloom uv bloom uv. I'll just skip it till the seedlings are older.
