How Many 2 Week Clones Under a 400w?

Howdy,

I usually run a much longer Scrog, but this summer, I have to accommodate a vacation, and can only veg for 2 weeks after they have taken root.

How many clones will fit under the light? This is Barney's Blue Cheese in a soiless grow, btw.

Thanks ahead of time for your help.

If in containers smaller than 3 gal. I would say 9-12 since they shouldn't be huge.

Thanks. So far, the 12 cuttings I took are doing well, so I'll keep working with them.

I figure I may try a bit of lst, but nothing that causes any damage (topping, super cropping), since I have such a small veg window.
