Thanks, I am a fan so far.
I dont pull out the roots or even the stem. I just chop it as close to the surface as possible. Its normally gone in a couple of weeks.
That is a big ass pot to transplant from. Never really transplanted after i went from 1 gallon pot to final home. Thats a big root zone to manhandle lol.
I have also gotten a couple of people started with the tote method for living soil. Its a great way to slowly build a volume of soil for a bed. However I normally steer them toward 32 gallon totes with 2 plants per tote, 1 tote per 2x4 space scrogged. So a 4x4 would have 2 totes in and 2 totes resting waiting for next round. With the 3 people I have set up like this they have each had 2-5 good consecutive harvests. Pop the lids drop in 2 clones/ tote and away we go. They only veg for 7-10 days before they flip. Transplant from 1 gallon pots. However these guys are not hobby growers. We're all elder millennials(38-34) working a shit ton and just need our grows to be pretty hands off. We have found this to be the best way. Big beds, auto watering. My bro in law just dumped his 4 totes into a 3x3 bed. He's excited.
