Greenhouse/potting advice

Relatively new to growing, yet have some idea what I’m doing

Few quick questions

What finishing pot size should I put them in before flower? Outdoor green house flowering starts in abour a month

After I confirm the females I’m thinking 15-50 gal smart pots depending On the size of the females.

- running out of room in my greenhouse and it’s for privacy/security so I’m thinking maybe keeping em in smaller but I think the more room they have to grow the better.

Once I can confirm all the sexes I’m collecting pollen and killing the males to make room and filling it up with fems in bigger pots

Input? Advice on nutes? Training?

I use fox farms soil as base usually of or happy frog then I put abour 30 percent coco coir 15 percent perlite or so mycho inoculat 25 percent compost and then some slow release fert

Train em when I have time input advice? The size difference of plants is due to start time everything started from seed 3/28 to 5/1 the plants in then back are taller and bushier

Pot them up before flowering and just do it in the smallest final container you can live with. The larger the container the slower the initial growth.

Buy Jungle Juice by Advanced Nutrients and follow the schedule on the jug.

Buy General Hydroponics Cal Mag and use every other feeding from the start.

Training why? Height control use supercropping or LST and I suggest either to keep eyes off.

Depends what your final goal is. I have several greenhouses. I personally don't feel the need to go over 40 gallons. I can achieve monster plants in that size pot without taking up to much floor space or ceiling.
