A video log of growing tomatoes hydroponically. I will be updating over the weeks to show progress. Items shown can be seen in this Amazon list: You can get the bucket, lid and most other items also at Home Depot or Lowes Check back for frequent updates and additional tips Video Rating: / 5 This video shows how to set up a non-circulating hydroponic system, a.k.a the Kratky Method. I use rockwool to grow seedlings and then net cups and clay pebbles to plant the seedling into containers filled with water. The water contains a hydroponic solution to help feed the plants the nutrients they need. Two solutions are shown, one that works well for leafy greens, the other for fruiting or flowering plants. You will see the Kratky method demonstrated for three different plants in this video; lettuce, cucumbers, and tomatoes. All of these can be grown successfully using the Kratky method indoors with little effort. This video is meant as an introduction to the Kratky Method, if you would like more detail then check out my other videos on the specifics of each type of plant. Experiment, and most of all have fun and enjoy the satisfaction of growing your own vegetables!

    Van we use gravel instead of clay pebbles? And what would be a good rock wool substitute? These are not available in Jamaica

    Do you ph your water? If I don’t ph my water, will I still yield good results? Do you ph your water with Foxfarm food? Or just feed it to your plants? Thanks, love your videos!

    Just want to say, I love your videos! Since the ecoli outbreak on lettuces, I started growing my own lettuces and microgreens, and I'm happy to report that everything is growing beautifully. I've used many of your soil vidoes, but you have me interested in Kratky, so I'm going to transplant a few to mason jars today. Thank you! <3

    You confused me. You stated to add calcium sulfate, but the bag was ammonium sulfate. Huh? Also, without covering your jars, algaebwill grow and eat up yoir fertilizer, do you cover them?

    In my opinion there is aeration in the Kratky method. It's the part between the netcup and the bucket lid that is the aeration in kratky method. It's not the type of aeration you'd get from a pump but it is aeration for the aerial roots

    Looks like your water is too high. You need air underneath the soil, hence use wicks for immature plants. Also, you should use less rockwool so you can cover it completely with pebbles. Algae likes rockwool.

    Could you use root riot or rapid rooter instead of Rock wool?
