RE: [Spam] RE: [Aroid-l] Anthurium

From: Skip Hanson shanson at emc.com> on 2006.11.21 at 15:25:00(14817) ? Chris, I have been using a "self venting" propane heater in my 8x12 greenhouse for years without any ill effects on my Aroids. However, I noticed a few years ago that my orchid flower buds were turning black and falling off. I started moving more air around with a few fans and added an attic vent. It's nice and cozy and no problems. I keep the temp around 68 F throughout the Winter here in Northern CA. I don't grow many Anth. that can't take less than 70 F...bunch of wimps [:).

You have given pause to worry now! But then, my greenhouse is fairy small (17 feet x nine feet with an eight foot peak), and I have a strong exhaust fan, a good circulating fan, and three sliding glass windows that I use for vents, one of which is immediately above the heater. Is the temperature range I mentioned in my last missive reasonable for the Anthuriums? Happy Thanksgiving, Christopher AUTOTEXTLIST \s "E-mail Signature" D.

You have to be concerned with the combustibles because as I recall we caused leaves to fall off plants by using a burner within the greenhouse.

Christopher RogersSent: Tuesday, November 14, 2006 11:34 AMTo: Discussion of aroidsSubject: RE: [Aroid-l] Anthurium Dear Tom, Thank you for the advice. Anthurium is a new interest of mine, as I typically have been focused on the tuber bearing aroids (Amorphophallus, Dracontium, Anchomanes, Cryptocorne, Arum, Typhonium, etc.) But, I am pleased that my Anthurium harrisi has just pushed out its first flower. I am trying to keep the light levels the same as what the parent plant has. The parent is in a whitewashed greenhouse under a canopy of tree ferns, orchids and Monstera. The leaves on the parent are nearly black with silvery white veins. The two ‘babies’ came from the base of the main stem, where there was very little light penetration, and these leaves are very pale green. So, I am a little concerned about them being burned. I have them under my son’s orchid bench, in a high humidity (80%) environment, with the orchids that need low light conditions. So, as our winter sets in, temperatures in my greenhouse run from 12 degrees C at night to 26 degrees C during the day. I am installing a propane heater that will keep the temperatures a bit higher. Any further comments or suggestions? Thanks, Christopher D. Christopher Rogers Invertebrate Ecologist/Taxonomist ((,///////////=====< EcoAnalysts, Inc.

If you bring it up too high in the greenhouse the light would be better but it could be too hot. Obviously plants respond favorbly to light, not darkness but the temperature control must be monitored because if you have nice humidity with too much light you will develop too much heat. Alternatively conditions too dark might not work either. Clearly regrowing sick or weak plants is a slow process some times.
