Lets say you are running high yielding genetics. 30 plants in 15 gallon during summer. I cant find any information on what poeple got from a 10x20 green house grow.

Unless you start your plants late (May-ish) then you will run out of room, even if you do start in May you'll run out of room.. assuming things go as they should of course.

Those are 5 plants, started with 9 in March. 2 flowered early and got chopped, 2 died on me due to lack of space.

I'm in a 10x16 greenhouse and even with just these 5 plants I have no room left. They were planted in holes, each hole fit roughly 20g of soil in them. No way you can fit 30 plants in a 10x20 greenhouse unless you don't veg them out at all and plant them in like late May or early June before the solstice. My greenhouse started at 7ft due to space limitations, but even then I had to increase the roof by an extra foot. I'll be moving next year and when I do my greenhouse is going to be at least 12ft tall and even then I have my doubts as to whether that will be enough height or not.

Have you grown outdoors before OP? I'd recommend cutting things down to 12 plants in a 10x20 greenhouse and observing things. I've had 7-8ft tall plants before outdoors, but never did I think these plants would turn into full blown trees and that 5 plants would use all 10x16 of my greenhouse, but here I am haha

You could have light dep'd your greenhouse and then you wouldnt be where you are at. You can put any number of plants really into a 10 x 20 greenhouse .. just depending on size .. and how big you want them. Then you start the flowering process besfor they become monsters and grow into the ceiling.

My limit is currently 12. I'm much better off letting 6-12 plants grow into trees, then doing light dep during the winter, as opposed to doing 3-4 light deps a year. On top of that, you can see how I built my frame. It wasn't build with light dep in mind, so I'm unable to take advantage of it personally.

I didn't offer any recommendation on light dep because in my experience people on here tend to specify if they're doing light dep or not. If he's going light dep, then sure he can make 30 plants work. But if he's planning on doing a full outdoor cycle then there is absolutely no way 30 plants can be done in a 10x20 greenhouse.

Why chop the ones that flower early?

I didn't have the room to let them finish, the other 5 were just getting too big. Even if I had the room, re-vegging plants that flower early is more trouble than it's worth in my experience. Easier for me to chop them, blast them and make edibles or something, then start from a new seed/clone.
