to many plants to scrog with the size of your tent. if your flowering now expect 2-3 times the size they are now. it might get a little crowded in your tent so trimming leaves that dont receive light is highly recommended and will help increase yield.
Yea mate I'm on my firs grow and have also got cheese in flower (15 days).i have a slightly bigger area than u (6ft,3ft,6ft) with 4 b cheese and 1 sleestack/skunk1 and I am finding very tight at the minute.i couldn't believe the hight and bulk mines put on in only 1 week have a look.getting very busy in their and yours will aswell.
lollipopping helps yield as the plant doesnt need to focus on areas with little to no light, and focus more on bud production. thats why when people scrog they also lollipop so they dont have to worry about popcorn buds that take a lot of energy for little gain
