If you think they're photoshopped you're uninformed. You can find these types of grows verified on many boards. I have a couple years of experience on you and much more knowlege in the subject of large plants than you. I've already cropped many indoor plants taller than 8' and they would have kept on going easily if I had the space and lights for them. I've posted several taller than my ceiling, look up my past grows...
Here's my smaller simplest and cheapest old single 1kw grow that I put zero effort into when I first started experimenting with large plants. This is just starting flowering, not even half way into flowering and I don't know if you can tell, but half the plants were falling over in this pic because only the one in front was tied up to show it's size and only with a couple strings at this point. I didn't take finished pictures because the room ended up like spaghetti and really ugly, I had to put string up everywhere to keep the branches from snapping as the weight packed on, and the only stuff you could see to take a picture of looked like shit because the outside parts stopped getting any light as the inner branches thickened up. I didn't have nearly enough light for them at this point, but I got what I got:
That shittiest and simplest large plant setup I ever did yielded over 2lbs. The thread is titled zero prep budget grow, or something like that. I also posted larger plants I grew in my tiny bathroom, they passed ceiling height easily, but I don't remember the name of the thread title and with over 6k posts it's not easy to find. The largest 8'ers I did were with 2kw stacked open bulb vertical in my garage, vertical cylinder scrogged and yielded 3lbs per 1kw. And none of them I did hold a candle to what can happen when you stick one like in my pic above outside after it's too big for indoors.
There is a very simple trick, and I told you how they did it already. They simply vegged them big indoors before the outdoor season even started, then they went all season outside getting even bigger until flowering set in.
When you give the right strains a longer grow season than is ever normally possible on this planet, california climate, and over 55 gallons or more of root space they just keep on growing bigger they don't ever just sit there and stop at 5' tall or 10' tall or any set limit.
These stupid big plants above really are easily attainable given the right circumstances and strains. You do notice they had to put that webbing over them to keep them from snapping right? Can you see the size of the squares, he could fit his head in there.
Just think how much work it would be to photoshop around all the detail in front of and behind those things without leaving even a trace of editing. Around every cola and around every individual leaf. Please... Those sized plants aren't even all that unusual these days in many areas.
There is a house and barn in this farm for size comparison, each of these plants are easily bigger than a car, compare to the two lane road not just the driveway.
