When to thin out??

[sdw79]

I am getting all kinds of sprouts in my 72 cell tray, I put two seeds per cell, how big do I let them get before I separate them?

When they get about an inch tall you need to get them under the lights.

I already have them under lights, but if I have two seedlings in the same cell when do I separate them?

Now.

are you looking for twice the number of plants or just one plant per cell? cuz if you're just thinning don't even pull the guy out, just go with little pinky shears and cut the stem of the one you don't want.
but yea, now is good...

I usually wait until they have the embrionic leaves nice and big. Then I pull out the least healthy looking one.
