you seem to have lost the meaning of SOG, clones, not individual plants from seed.
you have quite a set up there, but your plants will outgrow the space quickly during veg.
ya see, a single stemmed clone, single cola, is the mainstay of SOG, individual plants from seed will have many branches which will fill your space faster than you can keep em pruned up.
this is just my opinion, but if you want to do a sog seedplant grow, you need to start the force flower period near the 3rd week or they will over grow your space and give you a tsunami grow
just my opinion, but who listens to an old grower, smoker
all in all, i would love to see you succeed in this and prove my growing experience wrong.
GOOD LUCK
keep up the good work
