Mine would be HF. I will check out the HF blog. Didn't realize they had one. I've pretty much decided I will add one more GH and then I will have a 6 x 16. I will remove the door between the two and replace with solar pool roll up. That way I can keep all the plants that need warmer in one section. I will put planting areas in the ground in one of them (totally solves that problem of what containers are "safe") with a brick walkway.
Of course when I say "I" I really mean I will help my husband who is always the "consulting engineer". Haha
Thanks for the HF blog info.
