Two 2 foot t12s.

I am starting my indoor grow and have 3 seedlings about a week old. I have them under some t5s. I think 400 watt. 4 bulbs x 4 feet. (Overkill I know, it’s all I had). Anyways I was cleaning up my garage and found some brand new 2 ft x 20watt t112s. 2 bulbs for the fixture.
my question is. Are these enough to grow my seedlings for a few weeks or should keep my babies under the t5s?
thanks in advance.

These are the t12s

These are the t5s

Keep under the t5s. Seedlings are fine about a foot (or more) away from them at first, just make sure they don't get too warm (with the temps outside as they are, these do generate a bit of heat). Each 4 ft t5 is only about 50 watts, I forget the exact watts of those bulbs though, maybe slightly less. It's not 400 watts, no worries!

T5s (in the 6500 color range) are fine for veg. No need to change.
Three plants would outgrow the 2' light pretty quickly anyway.
Keep on truckin'
