Hey there my dear Grow colleagues! These Tropicana Cookies Autos are now 8 days young and reside in about 1/2 liter “pots”. Maybe comparable to a solo cup.
When do you think I should move them into their final 3G homes? I don’t want to be too late but not too early either, for I want to get a good sprinkling of Great White and Azos on the roots..
Thank you for your knowledge in advance!
Two of them have a slower start, so the focus in on the bigger ones now.
Every time I start in a smaller pot and transplant, they end up stunted and not as nice as ones I start in a pot big enough for entire grow. You could move any time, really, up to 4-5 weeks, even. It’s also fun to leave some in the small pots for entire grow and get a bonsai plant with one or two nice buds on it. Autos don’t seem to like their roots disturbed at all, so letting them get fully established before moving to bigger pot is probably best, ie. 4-5 weeks. At 3 weeks, they don’t have much root structure and all the dirt will fall off as you move them.
You’re going have answers all over the place with this one my friend 
Auto’s transplant or not is a on goings debate and even amongst the transplanters, it’s debated when
I typically transplant once the leaves are over the edge of the container (usually a solo cup).
Sometimes sooner sometimes later I don’t stress to much over it myself.
@akman I’m doing the transplant method mainly to hone my techniques for the outdoor season which is my main “mission” every year.
With these milk cartons I have always just cut the bottom off and slide the carton out while the plant sits in the transplant hole. Usually no disturbance or crumbling of the rootball.
I want to avoid the taproot hitting the bottom and starting to circle around because I read from many places that will trigger the flowering. That’s the difficult part in my mind, to get enough roots to get contact with the mycos and azos but not to trigger flowering…
I have had great luck transplanting both Autos, and photos. I also use ample Great White and the plants never seem to miss a beat. I would probably wait another week on those young ones. Prepare the final pots now and start “tempering” them with whatever you are feeding the seedlings go the soil conditions are as close as possible.
I’m just brewing a compost tea and goi g to saturate the pots tomorrow. I’ll keep them moist until transplant.
Roger that! I do similar, and have fun every year trying to time the weather. Too cold in May, and too rainy in August, so I start them around 4/20 in the house, move to greenhouse at 3 weeks when they start smelling up the place, lol. Then a couple weeks transitioning from greenhouse to outside in the sun, then can usually put in the dirt around June 1st, hopefully getting some nice buds before the rain and mold get here. I like starting in 1 gal pots and cut the bottoms off for final placement in the dirt. Seems like keeping them in the pot with about half buried gives them a really nice home to finish off in real soil.
14-20 days is my norm from solo cups to 3 gallon pots 
Autos are gonna flower when they’re programmed to flower. The only trigger is when their DNA says it’s time.
