What do you think?


  1. Okay I need to know. From 0:53 to 1:07 you have the container with zero soil it seems and just a mini grate or something with just water up to the brim. Whatโ€™s going on there and how does this work?

  2. Thank you for your educational video. My first time into hydroponics. Something is missing in your calculation. 10 grms of master blend tomato, 2 gr of calcium nitrate, for a grand total of 20 gr so is 10 fr of calcium or the other 8 gr is from something else. hope you reply back, as I am on my way to the store.

  3. I love the passive hydro build in a downspout! Have been looking for a good option to fit in my window sill and I believe this is it. Have you had any issues outdoors with mosquito larvae?

  4. I noticed you grow mostly leafy greens…If I were to purchase the nutrients you mentioned in this video would it also work for peas, beans, corn, squash, peppers, etc.?

  5. Hey Mike, great info. Can you please verify if the water needs to be changed or just topped up. I was concerned about stale water. I am planning to make a 4 foot vertical tower for indoor use and use a pump. Thanks again.

  6. so how do your plants survive without oxygenation? Even passive hydro like the dutch buckets supply oxygen to the root system because the perlite traps tiny oxygen bubbles.

  7. Hello from Sydney Australia! Thank you so much, you're so inspiring, i'm shopping tomorrow and get things started. Just need to do some googling now how to grow the microgreens ๐Ÿ˜€

  8. Cool! Thanks for the info, Iโ€™m living in an apartment, with a tiny patio and I really wanted to do some hydroponics, and this is perfect!๐Ÿ˜Thank you so much and God bless.

  9. Ordered 2 from you & can't wait to set it up…I just gotta get get a 5 gal bucket & ready to grow. Absolutely fantastic thank you! You are the change ๐Ÿ™๐Ÿผ๐Ÿ’š๐Ÿฅฌ

  10. Did you make the beautiful wooden and marble planters/grow boxes at the beginning of the video? If so do you have a video with instructions? This way people can grow them on their kitchen counter or their table in a window. Thanks a fan of yours, Eva

  11. Ok so I bought the pool noodle. Same color as yours. Dumb question… What size hole saw do I need? My seedlings are growing, it's emergency ๐ŸŒฑ๐ŸŒฑ๐ŸŒฑ they need home.
    Watching your videos in mute, kids are sleeping, can't find earphones…

  12. I see on some Dr. Kratky's recent videos, he's been planting his seedlings WITH the soil still attached when he puts them in 3" net cups. I realize he is doing this to keep mosquitoes from crawling up and out through the net cups, but it seems like it might be less stressful on seedlings if you plant them with soil attached. Your thoughts, Mike?

  13. Hey Mike! Thanks again for this solution! I tried planting tomatoes and cucumbers and Swiss Chard in a 3 downspout setup. In the Cali summer, you have to water every 2 days! I guess not a good solution for Cucumbers and tomatoes except for going from sprout to small plant. I transplanted all into Dutch Buckets except for Swiss Chard which are doing great!
