I think I made all of the mistakes the first time I started tomatoes from seed:

1. I started seeds too early.

2. My light source was not strong enough.

3. Plants were not properly hardened off.

4. Plants were planted outside too early.

I was saved by a nice warm, sunny May and the bubble wrap idea from this Forum which got me through a few nights in the twenties.

My plants look good now. Bloody Butcher has opened flowers and most of the others will flower soon.

Thanks to all here
