i donno man ive tryed puttin a unrooted clone outdoors aswell as other plants and they just dry up way too quick in the summer sun. gotta root em inside if ya ask me. ive started seedlings outside with ease just gotta not have em in a LOT of sun for long periods of time make sure they get plently of water etc. i also kept em in a plastic box with little openings on top. lotta things outdoors will fuck up young plants, lotta bugs thatll eat sprouts like slugs, i once had a ant bite down one of my plants like 8" tall, gotta battle deer and shit from feastin on em where i live lol. Starting outdoor can be done my friend. As far as a good cloning solution i dont do a ton of that i just picked up some random stuff at lowes it worked aight. You could also put em in your fish tank and put like a plastic cover or somthin over it ya no. Just keep a good eye on em outdoors when there young shit can happen quick.And humidity is good for plants when there growing, not the case in flowering.You really should start em inside a week or 2 but its not nessescary if u ask me. Lol ok phew....Good luck to ya ill try to stop in and see if you got anymore questions. ~ and as far as your last question im not sure if cannabis is capable of that, however i may be wrong, i know blackberry bushes do
