I brutally removed most seedlings that didn't look good. It was hard for me, I'm the person who always wants to save everything. I keep hearing about plants that get stunted and survive, but never really become productive. I have seen this happen a few times, so I decided to start over. Strangely the Tomatoes did the best.
I was quite impressed with the first set of soil blocks I made, they were easy to make, looked perfect, and really held their shape. I didn't like how hard they were to water properly. I'm sure with practice I would eventually figure it out, but starting over now is very late for my claimant, so I'm going back to what worked for me in the past. I added a good amount of sifted potting soil and a sifted bagged compost to what was left of the first recipe.(I wanted to lighten up the mix, and maybe have less biology? ) I was sure this was going to make it much harder to make my soil blocks. It didn't. The technique I learned make a huge difference. The blocker was easy to fill, made perfect little blocks, and I didn't have to rinse the blocker after each one. The blocks look good, but definitely aren't as firm. My first batch I could toss from hand to hand and it would keep it's shape. I'm pretty sure these would fall apart if I tried that.
I will restart all my peppers, some tomatoes and and some herbs. Who knows maybe starting later, and having plants in pots a much shorter time before they can go into the garden will end up being a good thing, time will tell.
As for the 2" blocks I have greatly reduced my watering, and the difference is amazing. The seedlings are growing and putting on more leaves, and no more soil gnats. It's surprising how fast things turned around once I realized my mistake. Of course I wish I would have figured it out sooner, oh well. It probably hasn't hurt that it's warmed up a lot too.
Wish me luck for round 2. Thanks
