Just for grins... I am an only fair-to-middling grower of this group, but my success rate is definitely improving. Mine move out of the GH once night temps are above about 55 deg. F/13 deg. C, for those with good growth, but that's around April or early May when days are getting longer, brighter, and warmer. They stay inside until they're pretty leafy, and ready for a full dose of water. At that point they also get a good top-dressing of time-release fertilizer since they're in rapid growth. The GH isn't very bright, so perhaps the increased light compensates for the somewhat lower temperature. At any rate, they're growing like crazy now. (This procedure is also somewhat driven by necessity... GH space is very limited, and as those leaves get large, there just isn't room for everybody. It all seems to work out.) Now, my night low temps are around 65 deg F/18 deg F. and some of the Catasetinae (Ctsm. expansum especially) are 2 ft/60 cm tall or maybe more and still growing fast.

Again, thank you for the assistance and added knowledge. will start watering now in stages will add fertilizers too.
