But a #5 pot's decent size for indoors. Too big for a 3-week-old plant, generally--the soil will get nasty before your plant can drink it up. When are you counting your "veg days" from? When you plant the seed? When the seedling first breaks ground?

You could grow a 3' bushy plant easily in that container--taller than that, and getting light through the canopy starts getting hard when you're growing multiple plants. So it doesn't make sense to me to try to grow them taller. Folks with plant number limits might need to grow trees. But if you're flipping them at 3 weeks a 3 gallon container should do it.(?) Maybe that's too much for me to assume, cause I don't know what plants you're dealing with or which soil you're using. I could be wrong...:hippy:

Edit...Oops...you guys posted while I was typing...
I'm one of those with plant limits... I may end up vegging a bit longer to try to increase yield. These were rooted clones that I transplanted from a small starter pot to a pot that is about 6" tall, 6" across with FFOF soil (10% perlite added)... I'm guessing it's a 1 gal or maybe 2 gal. I was planning on vegging in this for about 3-4 weeks then transplanting to the 5 gal right when changing to 12/12... The 5 gal is only a little wider than my current pot and a lot deeper. I was told that would be adequate...

But from reading on here it sounds like I want to do another transplant in between to a 3 gal? I was hoping to avoid this... I didn't want to buy more pots and I didn't want to transplant during flower... But do you think this will be imperative? I was going to add a little bit of dolomite lime in the 5 gal containers since they'd be in there for 60-70 days.... and I'll be feeding throughout flowering.
