I've had all three for about 8 months. The sandersonii plug quickly fiiled its pot, and bloomed very profusely for a month or so. Since then it sends up just a few spindly flowers here and there. The bisq. initially sent up a few flowers, but hasn't done anything in months. The livida just occasionallysends a few up.
They are under 4 32 watt t8s for 16 hrs a day. Temps of 65 -80f. I will flood their trays up to the top of the soil line, let it drop to the bottom, then refill.
So how do I get (and sustain) the profusely blooming pots of these like those I've seen pics of?
