ive used everything from pots with plastic bag over to box with some plastic foil over. overall cloning is easy, but some strains are a bitch
. also try to take clones from part of the plant were the stem is not woody but fresh. clones with woody stems are harder to clone then clones from fresh growth. also just let the be inside of whatever you have to up the humidity. when i first started cloning it sometimes took me 3-4 weeks to get rools but now i average 7-14 days depending on strain. i never used hormones, but i figure its not necessary since i have about 95% clones make it. but when i was noob... below 50% xD. also remember to cut tops of fanleaves, this will speed up the process at least 3-4 days.
just keep trying stuff and you will find a working plan i promist
. been checking your pics from time to time and your progress is amazing
. keep up the good work friend.
