  1. Thanks for the great question. 1) If you have digging machines, then consider installing pipes for a ground source heat pump. Once you reach a couple of meters underground, the temperature doesn't vary much, regardless of what happens on the surface. It is about 12Celsius. 2) Have a place and space for a hammock in your greenhouse. It would be a waste to leave such a lovely place solely to plants. 3) Consider hanging some LED growlights to keep things going during Winter. 4) The North side will likely lose such heat that it might be worth using multi-panel polycarbonate there. 5) You can use a water feature like a pond in front of the South side to bounce light into the greenhouse. If the water is saline, it wouldn't freeze during winter. 6) Consider a geodesic dome. Check out ziptiedomes.com and the brilliant Paul Robinson channel. 7) Space is often limited. If digging, dig deep and use trap doors to allow storage under the green house. 8) 6mm Polycarbonate twin wall is the best balance for allowing light and retaining heat, iirc. There are UV protection coatings now available. Frosted polycarbonate will disperse light and reduce "hot spots". 9) Plan for and automate ventilation and irrigation. 10) Consider a hydroponics setup.
  2. Is there a particular type of sphagnum that would be good for Sarracenia seeds? For example, would fresh sphagnum be preferable to dried? Does it need to be treated in some way?
  3. There has been some talk in greenhouse cirlces of using water butts as a sort of heat sink, to provide passive heating of a greenhouse. The maths don't work. The water cannot absorb sufficient heat during the day to make up for the heat loss during the colder nights.
  4. I am fortunate to have received some seeds from the Carnivorous Plant Society in the UK. They are "Sarracenia mixed hybrids". What is the best course of action to grow them? From reading around, it seems they would require the sunniest window and rain water. I have the impression that once an appropriate soil mix is found, all that will be needed is rain water. It sounds like the soil mix is important to their success. They are meant to take a very long time to grow, years and years. Is there nothing that can speed their growth? There are about 30 seeds, altogether.
