did you buy them? I used them but I find that the soil is too compacted for good seedling root development. They now sit on my top shelf never to be used again.

I have been growing my own cut flower seedlings for 5 years, on our cut flower farm. This year I have switched to a mixture that is more porous, similar to a 5:1:1 and I am finding that the seedlings are healthier. I have to monitor the watering but I am doing plug production so with the small cell size, I would have to do that anyway.

Hope this helps, good luck

Yes, finally I bought them.

For now I use only the mini 20 and I am pretty satisfacted about that. I have a little grow room inside my house and I can save a lot of space with them. On the other hand I had some problem with some seedling as you see in the other post. I think I have to practice more, and to learn a lot about starting seed. The next year I hope to have a greenhouse with no problem of space, so I can experiment more!!! I always buy plug of vegetable, but for annual flower plugs here in Italy doesn't exist.

Yes, thanks, always nice answer.
