Growing San Marzano Tomatoes in Kratky Hydroponics – Update: Week 2

San Marzano Tomato Seedling Week 2, In Kratky Hydroponics

One week ago I transplanted San Marzano tomatoes into a Kratky hydroponic container, and we were left wondering if they survived. Here is it in Week 1:

I’m glad to say that not only did they survive, they have started growing wonderfully!

The two tiny specks of leaves became much larger, and we now have four to five tiny new leaves beginning to grow on each section. The original leaves have definitely turned into stems, and hopefully they will eventually become branches.

The trunk of the tomato (can it be called a trunk yet?) is about three times the thickness than when I transplanted it. The fine fuzz on it has also thickened up and become much more apparent. I don’t know enough about botany to explain what this section does – if you know please let me know in the comments!

I’m not brave enough to lift the lid and look under. The water level was filled right to the brim of the container, and I mean right to the point of overflowing. I’m worried that if I lift it I will not only introduce light to the system, I may disturb the seedling as well. Maybe next week we can check out if there is growth.

Have you grown any tomatoes in hydroponics? I’d love to know your success (and failure) stories.
