how's the greenhouse, 2 months of trying
look below for pictures
My next experiment to master my greenhouse Humidity
have any of you tried to control low humidity in an arid region ?
(see below for my conditions)
I have ordered (with a 30 day satisifaction guarantee)
Top of Form 1

inside my greenhouse ======
Temp 69 - 61 degrees with two 1500 electric oil heaters running
RH has been 50 - 37 % now with two household humiditifieds running
(total output of .5 GPH)
I basically have 3 types of plants in my greenhouse
1. Bananas - which are dieing one after another
2. Elephant Ears - which are hanging on but not growing
3. Brugmansia - which are doing better than the others and have a few white flys which I am spraying as discussed on other threads
my climate =======
I am in zone 9 - 15 miles east of Sacramento California
for the past month my weather has been as follows
rain 3.7 inches
max wind 38 mph
low temp 25 degrees high temp 85 degrees
Rel Humidity 32-94
currently it is 2 pm and it is 50 degrees with a RH of 38% outside
other sources of advice =====
several sources that warn about excessively low humidity ======
1. "Greenhouses for Homeowners and Gardeners" ISBN 0-935817-51-4
Very dry air can reduce rooting of cuttings and cause leaves to wilt
Where plants are grown in very dry conditions, transpiration from the leaves will be greater than moisture intake by the roots. The growth and vigor of the plants will be reduced.
2. "Ortho's All about greenhouses" isbn978-0-89721-463-6
When Humidity in the Greenhouse stays below 50 percent for long peoiods, plant growth suffers, because leaves lose water faster than they can replace it.
Most plants do well with a relative humidity from 50% to 70 percent, but many tropical plants prefer 80 percent.
3. all references spend considerable time warning as Tigerlilly did of the risks of too much humidity
