My mini greenhouses worked almost too well! Within a week most things have sprung up, frantically seeking sunlight. I'm concerned things will get too tall and spindly by the time they meet the garden, so I removed the covers to cool them off a bit and hopefully this way condensation on the lids wont block sunlight. My mom suggests putting something underneath to raise them up to window level but I haven't figured that one out yet. Oh for the want of some nice 5 gallon pails!
