I would Just leave it alone pruning is only good when there needs to be room for multiple plants close together or some stains when pruned correctly makes for more yield or better Bud development. Just my opinion from 29 years of experience.
Ok is you have feminized seeds they were sprayed with a chem so they are all female.
If it's random seeds you will have male and female.
If you want the best weed to smoke with no seeds you have to take the males out when they show sex.
Now you want a giant seed crop let them all grow to adults
Needs budswell. Sprayed daily light solution would help in my opinion but I always have 100 like that but usually 15 to 30 inches. Plus you don't need that big of pot for that size so if you wanted to save some space you could use smaller pot. Just my own opinion and everyone is different. God...
I just put plant upsidedown in closet that is dry and dark. Slow dry till crispy makes for smooth nuggs. Crispy is how I smoke with torch. Popcorn fart crunchy that way you aren't smoking water. Just one way and it's far from perfect.
