So everyone knows that irregular light periods can cause hermaphrodite plants to produce male flowers. Is there a KNOWN photoperiod that will trigger this with 100% accuracy? I'm taking cuttings for clones that might be subjected to stress and I'd really REALLY like to find out which mums resist the male flower trait the best. Is there a photoperiod I can set my timer to to force out any hermie tendancies in my clones? Currently I'm planning on: 12/12 until flowering starts Then continue 12/12 with a 5 minute light interruption at 6hrs into the dark period. 1 24hr day of full light once a week. Any ideas what modifications to that schedule would cause hermies to pop balls faster?
Hey there. I have no personal experience with this, I just remember reading it somewhere. I can't even remember where I read it, sorry about that, so take it at face value. The piece I read mentioned changing 12/12 to 5.5 on, 1 off, 5.5 on. If I remember correctly, the piece said this had a pretty high success rate. Maybe someone else can chime in and let us know for certain.
Thanks C&H. That's the first new bit of info I've heard yet. Would that be a week of 12/12 first or just straight 24/0 to 5.5 on 1 off?
something i encountered, ill throw it out there i started with 12/12 for a couple weeks, had some nice females, threw them on 18/12 and saw herms in less than a week.
Dangit HydroGanic, now I'm really bothered that I can't find that article, and I'm going to have to hunt for it! haha IIRC, they did a normal 12/12 for a week or two, then shifted to 5.5/1/5.5/12. Hopefully I'll have a link for ya in a bit. EDIT: Back with the link. http://www.drugs-forum.com/growfaq/1638.htm Looks like you do the weird lighting for the first three weeks of flowering, then revert to normal.
Thanks! They must have updated the FAQ as I don't have that in my archive. We'll see how that goes as soon as I lightproof this little box (Don't need much to just force hermies!)
