Thanks Gene, I will put a moisture meter on my list. I'm using an organic seed mix by Espoma (?), it has perlite in it, but I mixed it 1/2 & 1/2 mix with perlite to lighten a bit more. I haven't had any signs others have reported and I am grateful for that. No brown spots or edges, no gnats, no wilting. I am not going to say it is do to my extraordinary gardening abilities, I just don't want them to rot like they did last year, so I've been been cautious about watering. I admit to being a somewhat lazy gardener so I have put the lid on the bin when I go to work and take it off when I get home - not going to time it to air out for an hour or two.
One of the cuttings is going to be to tall for the bin now that it is leafing out, so I am going to see how it does out of the container with no bag on it, if it starts looking wilted then I will put a bag over it. Time will tell!
