I'm still foggy on the reasoning behind this, so be patient with me ... if you're just trying to delay flowering, just leave the plant under 18 hours of light ... I gotta be missing something here :wtf: ... but, unless you're growing sativas, you should have plenty of time, to grow out two gardens a year ... that's a piece of cake ... in fact, with 50-day varieties, three harvests is easy ... regardless, good luck, sorry I couldn't help :smokin:
