I have had tomato seed failure, too. I only have 8 or nine tiny starts, but they are doing ok.
My grand experiment with coffee grounds taught me that ONLY garlic and sweet peppers like to grow in it.
Today I will be cleaning up the compost from 2018 that the cats dumped in my pantry. I keep Looking at it, and now DH, who has suddenly become interested in gardening since HE gets to drive the tractor, wants to spruce it up. I bought 2 more package of tomato seeds to start, since it isn't too late. We will go below 32 d F tonight, a bit late, but the average last frost is April 15th, and you should always plan for the date to go 2 weeks beyond that. I even remember a particularly cold May 5th.
The three "orphaned" kittens, now 2yo, get into E V E R Y T H I N G!!! ALL of my window planting areas get trashed bc of them. If they weren't so docile, they would get the boot. So...my indoor gardening starts has had to be more creative. I use my basement setup with gro lights, and the top of my fridge. They leave the basement alone, and can't jump to the top of the fridge unless they use the stove.
I found the New Yorker tomato seeds that Alex

sent me, including the nice note. I won't even try to start those until next month, when I can put them in the fish tank on the porch with the lid, so that I can REALLY baby them. Sure miss him!
