A couple things I have done that helps. I switched to rapid rooter plugs. Last month I finished 100 clones, 100% success with rapid rooter. They are cheap, $17/50 plugs at amazon.
Second, do not spray the leaves of the clones, just the lid/dome of your clone chamber. DO NOT over water your plugs. I usually check mine every 3 days and every 3 or 4 days, have to give a spray to the plug. You want them moist, not dry, but not too wet; they need oxygen or they will die. When I wet the plugs, I spray with a bottle and only wet the bottom half of the sides and bottom of the plug the clone is in. I do not spray the top of the plug or around the stem of the clone and don't overspray. If they stay moist, but not too wet, they will root.
I also like to root my cutting at the bottom nodes. I don't just want to root the stem (cutting the bottom stem at an angle or scraping it), but I like to cut off the new growth on the clone's stem and that is where I get my first set of roots usually.
If all other conditions are as you say, you should see your success rate go way up. Hope this helps.
Peace, God bless
Edit: I wanted to ask, your GT is not going into flower is she? Always try to take your cutting while the plant is in veg. It is difficult to root a plant going into flower as she is concentrating on flowering. It seems they need to go back into veg, before they can root and often (but not always), a cutting won't last that long.
What a beauty.
It's safe to say that here at 36.5° these finish on Halloween.
Glad To hear this Musigny. Was wondering if the more Thai influence in the current release would put me further into Nov here at 38N, it gets a little dicey for me past 1st week Nov.

Musigny,how deep are raise beds.
What diagrams of GTigers.
Between BCxP an the GTiger;Malawi dominant, which one was more vigorous !?
Musigny,I don't know if you did say anything on that pure thia,that you intent to cob,if so ,where may i (thread)find it!?
Has anyone finished GT (or Malawi) outside in freezing temperatures? I am curious how tolerant they are to frost/freeze. The fall weather has been perfect for the long flowering sativas, but a storm is coming with both snow and freezing temperatures. Last night dropped to 30F, and the plants are fine this morning, but it is going to drop to 25F in a couple of days. I have a little greenhouse I can setup for them, or can chop them (about a week early I reckon), but also wondering if they'll survive on their own.
Any input would be appreciated! Thanks all!
