New tunnel for tomatoes 🍅
So two now ready for this season. About 80 different tomatoes on the list - start sowing in 14 days 🤩☀️☀️❤️🍅. #tomatoes #greenhouse #diygreenhouse

automated passive solar floor heating for the green house is nearly ready. The passive solar air heater is still missing the black metal sheets, which need to be cut. The automation already works - nearly. The fan starts when the temperature difference between the heater and the floor is 10°C. Need to include a hysteresis to make it work properly. #DIYGreenhouse #Permaculture #Permakulttuuri #SolarHeating
