They are in 2.4 gallon #3 nursery pots. They are all vegged to maturity for 6-8 weeks. The cmh and Hortilux Blue are keeping them more compact. That and I learn to fertilize more closely to their needs. Things like phosphorous deficiency that you can't see cause stretch and long internodes. They are still all yielding over 4 oz dry solid nugs. Just shorter.
Here is a pic a while back with 2 hps to 1 cmh.

It was more dramatic before the cmh but most plants grew like the viney staked one in the left center. They were taller on average and flowered 11 or 12 weeks because of the long stretch and constant training and tying I imagine.
Here is tonight again. 1 hps. 1 blue mh, 1 cmh

It has been all compacting as I put new plants in flower under the new spectrums.
So I am now vegging longer.
