Hi guys, Also doing 12/12 from seed hempy buckets in 100% perlite / 2l coke/cider bottles. 250w HPS / DR 60 tent. I have not had the best of luck so far, ok i'm getting results but not great. Main problem is i purchased a "indoor indica mix" pack of 10 and the genetics are all over the place. Best so far was the 2 free "Big Bud" seeds which both turned out fem, i have one blue cheese re-generated back in the tent and a big bud regenerating on the windowsill. I also stuck a few Haze seeds in and have 2 fem that are trying to take over the tent. 10 weeks old and only JUST started flowering. bend bend bend, lol (still stretching) I've just got a EC and PH meter and my EC of tap is 0.6ec and 7.0ph anyone think that i should go over the recommended ec of 2.0 with Ionic nutes considering my background ec is so high (ie i'd only get max 1.4ec of nutes to bring it to 2.0) any help appreciated. i'd also like to know if 2l bottles is big enough for 12/12 hempy? any advise welcomed. BTW temps are constant 65 - 75*f give or take. Regards..
