First time window grower Q

Q: I'm a first time grower with 7 seedlings. Hoping to veg 3-4 2' plants under my bed and would like some advice as to what size container would be ideal when it comes time to transplant.


Check out my grow journal here <==

55 gallon drum

are you going to use soil?
and if so the general rule is one foot per gallon.
hope this helps.

I'm doing hydro right now and I kept mine in their 10cm rockwool cubes and they're a month into veg. If you're doing soil, then follow solar.
