Gorilla Glue #4 & Great White Shark Height

[DaveL]

Hi all.
I've just received the above seeds and will be growing them next grow.
Does anyone have experience with these?
My understanding is they are Sativa dominant height wise.
My tent is 76 inches high. Giving me about 4 feet usable space.
I intend to top or fim to try and keep the height at bay.
Any advice?
thanks

The answer is scrog, especially for yield. If you're not scrogging, then flower them at 15-18". How long you keep them under that mark by fimming and topping is up to you.

Thanks TysonOG. Makes sense.

Gg4 most definitely stretches good. I grew it for my first, second and third grows. It mega stretched on my 3rd grow as I used a different light and was in dwc.

Thanks.
When you say mega stretch, do you mean 2x or 3 x from when you flipped to 12/12?
My only experience is with White Widow and the stretch so far has only been about 50% which is fine and seems to be somewhat predictable. I've had a few grows.

I'll vouch for the GG4 stretch. That stuff tries to reach the stars lol.

Easily doubles in size and even as close as 3x it's size but that's if you have inadequate light distance or light strength.
