It should work but how will you light it? The sun will cook the cuttings.

Are you planning on using this in or outdoors? I have used one of them indoors for rooting cuttings as it will hold in the humidity. I hung a flourescent light in it to increase the light level. Outdoors it will get very hot if it's in the sun and also get cold at night, depending on your zone. Inside they are great though.

I have 2 of them and they are wonderful in a house. I also hung florescent lights on mine but I went a step further and purchased a heat mat for this reason. I love my geraniums. I use a root hormone before "sticking" them in the soil, and I have purchased a heat mat with a thermostat on it for consistent heat. I have to take the cover off when it gets too hot (a small thermometer can be hung in view to monitor the temp of the room and the soil). These can be placed in a garage during the winter if you don't have the space in your house. Or..If you need to keep it outside, get an inexpensive shade cloth at walmart and place over the "greenhouse" and use grow lights on a timer. This keeps the temps cooler during the summer and take it off during the winter but keep the clear plastic on to keep plants warm. A $70 price tag though?? Hmm. Makes me wonder if building it would be cheaper from Lowes. They have this plastic panel with holes that only costs $13 and it is a 48 X 60 and great for making a table. The rest of the wood can come from a construction site for the legs, and such. Consider your options carefully. For me, money is very tight and I lost my job due to cutbacks and war spending.

What is the plastic with holes called? What dept. at Lowe's is it in?

Lowes carries a four shelf greenhouse for $35-$40...Wal Mart, too. I got mine on clearance for $18, so do shop around.

I got one of these from Lowes for $39.99. I've had it about three years and it's held up pretty good. In fact, it's what got all this HFGH (10x12) stuff started for me - so look out!!
