Your plants and tomatoes look beautiful!!! I told you, you would have so many tomatoes you would have to start giving them away. Each plant must weigh a lot with all the tomatoes growing all over. You did an amazing job with your first successful grow, congrats!!!
I wouldn’t worry so much with temp of the
nutrient water. if you are able to keep it in low 70’s upper 60’s great. I’ve had my reservoir in the mid 80’s and tomatoes were still doing fine.
Make sure you save the
seeds from some tomatoes. Scrape them out of 2-3 tomatoes into a window screen type colander, rinse them off with fresh water until you get that gel off of them. Let them sit and dry on a cutting board for a couple hours. Use a butter knife to get the seeds that are sticking to the board all piled up and place them in a paper envelop for a few months and they’ll be ready to be used for a future grow.
I already have a couple seedlings growing won’t be able to get them in the 5 gallon buckets till mid May when there’s no chance of frost at night. We’ve had crazy fluctuations in temps the past 2 weeks up here.
