Hi, excuse my poor english but i like micro growing, and i think to start 12/12 from seed. But i have little info about it, could someone please tell me if a complete guide exist. I’ve konown that atmosphere from old overgrow was pioneering this technique, so would be nice to read also this old topic, if someone have in cache this threads.
