I don't know if I posted this here, but I know I posted it on my Permaculture Thread at
The thread "My PA Food Forest" in
Permaculture forum
Long story short...you may have noticed in a few pictures that I no longer had the PCM's on the wall where the reflectix is. I thought they seemed extremely sluggish in melting, and the temperature had to be higher than they advertised. Turns out they sent me the wrong ones (mis-marked for melting temperature-they make PCM's with several melting thresholds). I contacted the company and sent one square back for testing (at their expense). They confirmed it wasn't melting at the temperature it was marked for. They told me to dispose of all 63 tiles (over $1000 worth) and sent me new ones. I just haven't put them all in the greenhouse yet, since it is already getting warmer. The ones you see in the picture are some of the new ones I just put in today. All that initial work down the drain.
I was so happy the company readily took responsibility and did the right thing.
Here is what I did today:
And I have to start cutting and applying black contact paper again for better heat absorption when the sun hits the tiles.
Even though I planted Yellow Yarrow seeds for the greenhouse for attracting beneficial insects that eat some pests, I decided to accelerate that process and dug up ONE of the Yarrow I started two years ago and has been growing in the Food Forest. It is just starting to come back for another season. This is from one plant.
The greenhouse is coming alive for Spring!
