So I thought it was time for an update.

The Multi-plant pot is doing very well as well I believe that we have worked out our system for growing.

The first pic is to highlight how small the internodes can be when using the T5.
The second is the 5 gallon pot with two plants in it
The third is the LST method we are using. Which I recommend
The forth is a plant which we are moving from the T5 to the MH

This method is working so well for us, i feel the need to share:

The method we really like is, growing a plant under the T5 to the size of pic 4
(ideally with the internodes of pic 1)
We then top the plant and make a clone of that. Let the plant recover
Then we transplant the lil guy into a big 5 gallon pot but we don??t keep it in the center.
We plant her right up against a the side of the pot, so that we can bend her over and she??ll wont invade other plants space.
Since she was topped her side shoots should take off.
Finally, bend the plants main stalk over so that it is horizontal. And tie all the large side shoots out to the edges of the pot.

We??ve found that the plant hardly stalls it??s growth during topping/LSTing
