It's been 7 weeks now since I checked my clones. Looks like they rooted really nice.
The weather conditions are not perfect, 18 degrees by day and 10 degrees by night.
But the clones do not seem to have a problem with it. I will not check my clones every week because I don't want to get busted :p. I have 7 more clones @ home that grow behind the window,they will be topped and planted in the forest after 2 months..
