Hydroponics | Easily Grow Lettuce

Hydroponics | Easily Grow Lettuce

I’m really enjoying growing Lettuce in Aerated Water Culture, aka Kratky lettuce with air added. Water culture is the simplest form of hydroponic growing. Lettuce is a super-easy crop to grow in this way and is so rewarding. Why don’t you give it a try? Below is a comprehensive list of most things I use in the Winter Greenhouse. Many of them were used in some way or another in this grow.

MY STORE ON AMAZON. Everything I use for gardening, I try to put in my store including all my microgreen and hydroponic stuff.

Hydroponic Gardening & More with Brent


What do you think?


  1. How do you think spinach or possibly small cabbage would do in this system? We love spinach but getting fresh spinach growing in MN is sometimes a bit of a challenge! 🙂

  2. I do the same thing using plastic coffee cans. I highly recommend picking lettuce leaves from the "outside" of the head and not picking the middle leaves. Thus causing the plant to produce more inner leaves and form heads

  3. Man.. I’ve got to catch up with your videos. Oasis is the best! My germination rate jumped up to almost 100% when I started using it. Don’t turn down free samples. I have found some of the best stuff that way! Great to see you again buddy!

  4. Great video Brent! What is the best PPM and PH for the Buttercrunch that you have experienced? I saw you had some numbers in the vid here, but I thought you were referencing it to the cause of tip burn. Keep up the Great Vids!!

  5. Enjoyed this video!

    Thanks for showing your PPM I was gonna ask that.

    Do you use the air in your regular hydroponic solution also?

    Those net cups are very nice. I have bought stuff from them also. Good prices for the quality.

    Have a great rest of the week!

    Yall gro dat!

  6. Nice work! Your buttercrunch looks much better than mine. Mine isn’t heading up but it still looks pretty good, I will update soon. Thanks for sharing!

  7. Nice job. Where did you get all the creamer containers. You don't drink that much coffee do you. LOL. Been following you for several years now and you are a true experimenter and I love your work.

  8. I love the affect the emitters have by making the water appear as though it's boiling lol
    I love the "Kratky" method and think it's funny that Professor B.A. Kratky himself doesn't think the process deserves his name but excepts it lol
    I like his channel a lot.
    Great video Mr. Brent, the lettuce looks beautiful.
    Thanks for sharing and as always Keep Building👍
