SkankTank first time grower pics

Well, this is my first time growing everything is going well, but I'm beginning to think my plants might be getting quite big for the green house, also I'm not sure if the neighbours can see or will see my plants there around 4ft without the pot but with the pot roughly 5ft, i can force flower them but i think they will miss such a good opportunity of light since its July, but if there left to bud naturally they will be a considerably larger and easy to see than they are already... here are some pics, tell me what you think of them.

You might be able to scrOG them. A lot of people use this method successfully. Plants look nice. Good luck with your grow, cheers.

Cheers, it does seem a good idea, but do you think they might be a bit big for scrOG?
