Not sure but that guy said it was a tomato seed. I learned in medical marijuana class that if you have talk about conditions for plants but don't want to say the M word, then talk about tomatoes, since they have very similar needs and desires.

I'm thinking I might just drop a unit in my cheapo aero cloner, but not turn it on until some roots begin to show. Still worried about heat though. I'm not going to spend $450 on an aquarium chiller for my cheapo cloner, which already works pretty well.
