Im using those trellis nets 6" holes ,and I can tell you I was lazy and just tucked them under screen boy do i regret that because its a jungle in there. Im doing 12 plants in 1 gal smart pots in a 2x4 raised bed but the net is 4x4 like the tent. I realized I had to factor in the type of strain because scrog in my observation is mainly used for those dense low yielder strains like GSCookies ,Og kush etc.. Im doing GSC and thats why I put 12 plants in 1gals because the pheno I have is a shitty yielder but dam its fire! Also these plants are in the 1 gals for a about 90 days from rooted clone to harvest so no need for a big pot with that short of a life cycle in veg and also another reason why so many plants. If your doing a long veg time then do the 5 gal and maximize the 3x4 area with the scrog but also factor in all the stretch its all about timing with scrog!!
