They say that you should wait until the plant is at least 12 inches tall, but that, to me, will give you low yield. I'd say wait until month 2 or even 3. You can do it now I guess, but I don't know if you'd be happy with the amount of bud you end up with since the flowering period takes about 2 months.
steveat Reviewed by steveat on . vegging 30 days Hi I've been vegging my white widow for 30 days now and tonight I noticed my plant is showing signs of female(it was feminized seed so I already knew it would be) and its only around a foot tall and still on 18/6 light cycle,so I was wondering if it's time to switch to 12/12? I was planning on switching over at 5 weeks (in 5 days time) but as I only have a small grow box and it's alre ady shown signs should I do it now? Thanks :thumbsup: Rating: 5
