Transplanting San Marzano Tomatoes into Kratky Hydroponics

San Marzano Transplanted into Kratky, Week 1

So far in my hydroponic journey I have been starting my seeds in my Aerogarden Bounty; it has the highest rate of success. There is just something this machine does better than I can, which is also a reason why I recommend anyone interested in hydroponics without the scary setup look at the Aerogarden product range.

On the 1st August 2019 I planted some San Marzano tomato seeds in my Aerogarden. It’s been a week (a bit longer by the time I got around to writing this article, but photos taken on date) and it’s time to transplant my tomatoes into their final home. Exciting!

When I previously transplanted some lettuce between the Aerogarden and Kratky setup, it didn’t go as well as I hoped: my poor plants suffered a lot of shock. I since learnt that I had let the roots get too large, and the transplanting process really hurt the plants (by ripping the roots right off!).

After learning from all my recent plant murder attempts, I am transplanting the tomatoes the moment the roots emerged; one week after planting the seedlings!

Here are the tomatoes just prior to transplanting. The seedling wearing his seed pod as a hat is so cute!

My kratky container is the Klämtare Box With Lid from Ikea. It’s a great option as the plastic they use is food-safe. It’s also large enough for two tomato plants.

I used a 3″ hole saw to drill into the lid, since I was using a 3″ net cup. You could always buy a hole saw kit with several sized pieces (I bought one of these kits as well). I also chose to transplant from the peat moss to a cloning collar, though this was a personal choice. Underneath the cloning collar was clay pebbles; it is recommended to add some grow medium underneath the collar in case you ever need to remove it, as it provides significant support to the plant and sudden removal could mean the plant falls over!

Fingers crossed that the seedlings survive now. I’ve only transplanted once or twice, and they have all survived, but taken a bit of stress in the process.

Have you transplanted tomatoes, or any other plants? Do you have any tips to share?
