I transplanted a couple of my foot tall sunflowers outside about a week ago and they have grown about 4" since then. Inside they took around 2 months to get to 12", then 7 days to get to 16", they were also severly root bound though

I'll put my seedlings outside now, I can probably just leave them 30 yards behind my house with some screen around them so no animals get em.

Off to work on my earthbox too Xd
