Well my mat worked. I just sprouted three kinds of tomato seeds in only four days using it. I find that if I put a thick layer of seed starter mix about three inches deep in my seed starting containers the soil doesn't get too hot at the surface as long as I leave the containers uncovered even without a thermostat, but I did turn it on and off manually a couple of times. But now that many of the seeds already sprouted I don't think I will use it anymore as the seedlings don't need the extra heat.

I expect that the slits prevent "stuff" from getting out. (Only water.) nancyanne_2010 Being trained as a machinist, I am curious about shattering plastic with a drill. If one pushes hard using a dull bit, I can see where the plastic would break, but that would not be "drilling", that would we "forcing a steel rod through plastic causes it to break." (I would agree with you!) A sharp bit, preferably a brad-point bit, should drill nicely through all plastics. The brad-point on the drill bit will prevent the bit from "walking" when you are trying to drill through smooth plastic. MarkN

We installed a functional, commercial lean-to greenhouse with plexiglass panels against one ell of our house. Put in a gas fireplace and it is heated in winter and used year round. It is 12 x24 and multifunctional now. We keep it heated in winter, at one time it was used as an office for my business, and forced into use as a place to overwinter nursery stock for propagating. Since my business has been phasing down and is now phased out we simply use it now as a great buffer zone against the elements. My back door and two other household doors remain open to it year round. I have a fountain in there and hang ferns in winter. It has brick floors and is a great transition room from our outdoor activities to inside activities.......home for coat racks, boots and animals who shoot out our back door without leashes, lol. Gets a good amount of solar gain and helps our heat bills too. We have a ventilator fan at its apex to pull out heat, have a shade cloth we can use in summer, and a storm door for the outside entrance, so we can screen in summer. I can't imagine not having it now and it's a lot handier than the creaky old back porch we pulled off. It's like having both functional outdoor and indoor space added.

i lost my senior great dane girl 5 weeks ago to bone cancer. it was sudden and shocking and i still look for her. my remaining dane girl and eden were joined at the hip, pip took the loss very hard and had been grieving so much, it broke my heart. i contacted pip's breeder and one of her former co-owners and asked that they keep an eye out for any adults that any breeder friends might be considering a new home for (retired show dogs, etc.). the co-owner gave me the contact information for one of her people who had a dane boy she had been looking for just the right home for and the rest is history. meet "flighty foto my way", call name "frank". frank will be 4 years old on 5/31. he is a very sweet boy and he and pippin hit it off immediately at our meet 'n' greet friday. they do zoomies numerous times a day, sleep curled up together and are just a perfect pair. pippin is so much happier and that makes me happier. even though i miss eden terribly, i am beginning to heal now that pip is feeling better. frank is a bit on the thin side because he lived the last 4 weeks with a female dane who was going through a heat cycle and when that's going on, intact males ignore food, do a lot of pacing and fretting and routinely lose weight. he's eating like a horse so i'm confident he will gain and be back to his normal weight soon. i'm giving him a few weeks to settle in and then i'll make an appointment to have him neutered.
