First, I do not like rockwool. Probably me, but I have, time and time again, tried all kinds of methods with very little success.
I bought some Rapid Rooter plugs and had way better germination. But they are expensive, especially if one wants to start hundreds or even thousands of seeds. Then someone, I think it was Silver Surfer suggested the bio-dome plugs.
These things do not hold water near as well as the rockwool or RR, but in my first test, the germination rates are outstanding, the seedling growth is all I can hope for and the cost is very reasonable. I got the smaller size and they are not quite big enough to completely fill a 200-cell Speedling tray but close. I hope to transplant the basil seedlings tonight but let the toms grow to salable size to see how they work in the long run.
