Füst és hő-buborék a fák körül
Giant can candles, filled with liquid paraffin next to each tree, which is blooming in this period. These candles burn for 10-12 hours and heats the surrounding air. The heat and the smoke creates bubble-like microclime around the parcels, and keeps temperature above minus 0,8 degrees to protect the peach buds from the frost.
