a grower friend of mine, recently did a 12/12 hydro-growing experiment, kept a log, too ... healthy-looking little plants, frosty, etc ... I 'think' he said he got a 4-gram yield from his plant, if memory serves ... a lot of wasted time and expense (let alone, the legal risk) for 4-grams ... but, it was just an experiment, we learned from it ... :smokin:
