What an odd thought, what image comes to mind: the world of kerosene… And now I’m in it! Purchased new today, at a healthy 35% discount, this small, rather inexpensive, KeroWorld-brand indoor kerosene heater is the core technology in the extended-spring greenhouse plan. The idea is to turn the unheated hoophouse into a barely heated one, by warming it at night so that it stays above 38°F (4°C). That way, I can put out seedlings weeks early, instead of crowding them under scarce indoor lighting until it warms up in April. It should also give the earlier-than-ever lettuce, going into the ground in the greenhouse, a smoother start. This heater is low-powered—10,000 BTU, recommended for 420 sq ft, it’s 640 sq ft out there—but only a wee bit of heat is required. I think. Last year’s propane space heater was quite efficient, but burned too much gas for every-night use, it often went out by itself, and it required lots of ventilation. Plus, I don’t really like relying on pressurized tanks. This heater will hopefully burn low and steady, and it’s pour-to-fill! Aided by a fan to keep the air moving, and row cover on the coldest nights, it should get the job done. This all reminds me of Patrick of Bifurcated Carrots’ comment a while ago about the line between good and bad technology. It seems a personal decision as much as anything. Why don’t I dream about full-blown winter greenhouses, with high-intensity lighting and industrial-strength heating and ventilation, I wonder? Dunno. I just don’t. But an extra growing month in the strengthening sun, and a little less reliance on indoor lights, traded off against some kerosene, well, THAT would be cool!
