Has anyone ever tried to grow a plant inside a glass cylinder to constrain the vegetative growth? Could this be useful for a SOG? In case its not clear I mean a cylinder open on each end.

Sorry for my craptacular illustration

my guess would be the high output light needed to grow a plant that hits the cylinder would be so intense that it would be like holding a magnifying glass to your plant under the sun. so i'd say.. no.

nice pic lol, and in any case, that could be the point, to conserve energy and money...

Although since I have not tried this nor do I know specifically the exact science behind it.

Find some tubes and I will try it

Cut some cleaned out 2 liter cola bottles and use those for the walls. Good luck

I'll try this with my half of my new plants, we'll see what happens.

Poor so I will be growing with CFL's

What about a gentle breeze to make the stem stronger?

heard of a pane of glass instead of screen for Scrog. but with what your talking about the plant would be stunted because it needs circulated air, o2 would build up around it and the plant needs a lot c02, a glass or chicken wire cylinder around the plant would work and has been done, another form of Scrog, and in SOG the plants pretty much stay small and straight so why would you need to train them?

I guess he just wants to know what would happen, and as far as air is concerned I can run a fan down on them. I know not the best method, but stems aren't what I am after, I am after buds.

I said, if no one else has heard of or rather found anything about this, I will germ some seeds, and start a grow in this way, for the sake of finding out what would happen, and for the sake of interest.

oh and as far as the o2 is concerned, I am not super concerned about the plants building up tons of o2 with the top open.

it would be better to use chicken wire so it could breath better get lateral ventilation, but it will work, I know your after buds dude arent we all? but if your stems are weak and flimsy, your plant won't be producing buds at all just peices of popcorn. fan stimulation is VITAL, to thicken stems, thick stems=thick buds.
