First week of April 2020 Midwest Gardening.
While so many of you are in zones far warmer than Chicagoland (5b) we still battle crazy temperature changes.
We had a few days of really nice weather last week. This shows the wall temp(in the sun) roughly at noon. No need for a heater then.
At this point, we open all the windows and turn on the ceiling fan. These planters are under a shelf---and it's 91.9 degrees F.
We moved almost all the plants from the kitchen out to the greenhouse early last week.
I also started large planters of lettuce are on the floor on the west side. We have used paver base as a floor, it's fine for walking on and will absorb excess water. We are waiting to see how the drainage, heat, and comfort works with this. We may put some patio blocks over this--
for holding heat in the Fall.
I am going to try and keep the greenhouse
going for fresh greens and vegetables until December...we will see.
We should have purchased a heater in winter, because, now, Hubby didn't have much of a choice.
We had wanted one with a temperature gauged on/off switch, but none seemed available.
We ended up with a 2 ceramic rod 1500W heater, choice of 1-2 rods on,
and a wide temperature range dial.
How much electricity you use is dependent on the settings. We usually turn it totally off by10am on any kind of sunny day, and quite low on cloudy days. Even during clouds you have radiant heat penetrating through.
Excuse all the cords (12guage for the heater) everywhere. Not going for aesthetics, yet in the greenhouse.
The other purchase was a remote temperature system, which came with three sensors (battery) which transmit to a display screen in the house. We can see all three temps-most of the time, as they cycle at different times.
In the afternoon the sun can still be quite hot---however, once the trees leaf out it should be easier to control.
These gauges are very sensitive to sun...so we don't get hysterical unless all three temps register insane numbers.
The manual ceiling fan (3 settings) circulates the heat and also makes our plants stronger.
This is the indoor display...96, 72, 98...we know that two sensors are in the sun at this time. The bottom 74 is our home indoor temp(lots of windows in this house) and 48 is the humidity.
Last night was 27...degrees, and we maintained in the 40's with the 2 rods going at about 75%.
Now, I will go out and turn them way down, though the outdoor temp is still in the 30's as the sun is kicking in. (9:30am)
We found, prices range for heaters, $50-$200, ours was $79.
Prices for sensor systems are basically under $100 + the price of batteries. Lots are available with many options.
I'll never advertise any brands or systems, just giving you an idea of how much this little project ends up costing. These are multi-season investments. Our last greenhouse lasted us over 10 years, this one should be good until we are gone. We did burn up 2 heaters in the last 10 years---because of moisture issues, but the last greenhouse was a tent of sorts, this one is pretty much waterproof.
AND, that's why cords are strung up all over.
HOW ARE YOUR SPRING PLANTINGS, GOING?
HUGS AND STAY SAFE!
