I just ordered some LSD seeds, and can't stand the anticipation! Those are some dank looking nugs, and I know the smoke's great!
I've been running several different types from clones- mainly TGA's Cheeze Quake and Ripped Bubba, and a cheese strain we've dubbed Jr, in 1 gal cloth pots. I root the clones in small SOLO cups until they are about 5 nodes, usually around 6", then transplant to my 1 gal cloth pot, and goes directly to the flower room @ 12/12, and use Hygrozyme in every other watering.
I've found by doing it that way, the biggest advantage is the root mass isn't anywhere near what it would be if I let it veg in that same pot. Though it builds a nice root ball during the 8-10 week flower cycle, but the biggest part of a plant's root ball growth occurs during the veg cycle, and root growth is real aggressive.
The cloth pots help facilitate a large root mass by air pruning and not letting them circle the pot. That's a huge advantage! And the Hygrozyme enzymes eat up any dead and/or unhealthy matter, making even more room for roots.
After I harvest a plant and empty the pot, there will usually be plenty of room left in the bottom 3-4" for more roots.
The 7" tall pots, sometimes end up placed in another pot to keep em from tipping over! lol
I recently found some 5" tall x 7" wide pots, I'm anxious to see how that goes! Much more stable.
