My first grow I was worried about the height of my tent too so I switched to flower early and also by accident bc I didn't know I defoliated during the stretch. A bunch. And it stunted the stretch. Also some lst through the grow, pulling them down to even out the canopy. In the end I def had way more room to work with than I thought I would. But all together it made a low wide plant. I mean not crazy wide. They were only grown in 3 gal so they didn't get huge. Your plants look nice and huge. But maybe it's bc of the tent they're in. Either way you've done a really good job, first grow or tenth grow. Amazing what a bit of research will do. You can def tell when someone spent time learning about growing pot before jumping in. Not saying the latter is bad but personally I spent hours and hours on my couch at night reading articles and such. I'm not like sucking up or anything here but auqamans article about vpd helped out immensely in my grow. Understanding vpd seemed like it changed everything. It was pretty early on so I was lucky. I was able to take small stunted plants and got them to take off when i got vpd dialed in. Looks like you already do. Plus the co2, damn bro. Sorry this is getting so long, I'm just happy for the both of us. I'm just mid way through second grow now.
