Kama may be an expensive greenhouse, but the pleasure of consuming their own products that are not poisoned by chemistry can not be compared with anything. We have been using the greenhouse for the second year. Wintered well, but the snow was cleaned from it regularly, careful - God saves. The first dill was abandoned since the beginning of March, ascended very quickly. All seedlings from the first of April were transferred to the greenhouse. No dirt from the boxes at home. Last year, there was a tomato full, but they ripened in waves, now dense, now empty. Greens pulled almost until November, the first radish was faster than the market.
They adapted to reduce temperature and humidity by pulling agrotex instead of polycarbonate on the door. This year we are going to make two additional windows for ventilation.
pros
high-quality and reliable if you provide appropriate care
Minuses
additional windows are needed for full ventilation and maintaining the desired level of temperature and humidity (design flaws)
