Take a peak at @dmtscravey - he is using nets. Most everyone uses either some kind of packaged starter soil - Fox Farm, Black Gold, Epsoma Organic, Kellogg Organic…It is potting soil with amendments. You can usually get all the way up to flowering with minimum to no additional nutrients. We add things like teas, sugars, etc., along they way as needed, desired. I use 3 gal cloth bags. You can easily fit 4-6 in your grow area. I buy bags at Ace Hardware for 1.5cuft at 16.00 and usually have a 5 coupon. I add perlite (from Lowes at 5 a bag). You pretty much have everything else so a couple bags in the garage and you are set. I move my plants all the time. I move them to a table to trim, train, and even set them out on sunny days for a little R&R. Sometimes I will goto a 5 gal bag for photo strains. I only grow auto for the winter so it can all fit in my tent. I have 32 sq ft of floor space and a 6.5 tall tent so I can stand in it. No bending over for this old dude, I would crack in half.
I use pvc sched 40 and create a holder for my trellises when I do SOG. I do small ones, like 2-3 x 2-3 foot squares / rectangles, 4 to 6 uprights, open tops so I can move my nets up / down. Mostly I just grow with no canopy (except for trying to get each plant to have a canopy), no nets, I have plenty room for each plant and do not want the added time it takes to scrog, get around a trellis. I am happy just topping and fimming here and there and a few lst bends…Im good.
