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?
