Tafy, you're doing great!!! There will be some surprised friends that get to grow (AND EAT) some tomatoes!!!
All of them will remember Tafy's Tomatoes!!!!
Yeah, thin the numbers down gifting them to neighbors and friends, hold on to the "fittest of the fit", and enjoy the journey. If you run out of people to give plants to don't stress over the remaining "stragglers"...snip them off, toss the soil into one large container/bag for reuse and take care of your production crop.
Thinning can be a time of deep thought (as in Jack Handy) but once you snipped the culls it feels really refreshing as you know you can direct your attention then to the plants that will actually be giving you food!!! And, the more times you snip them...the more it makes sense and the hesitation gets less and less.
The grow tent might come in handy. I'm curious as to how they will perform without the tent. Maybe not a jungle of vines and fruit as it would be in 80F temperatures, but if they can make tomatoes on a mountain in Peru I bet you've got a good shot of growing some where you're at!!! Keep us posted!
