    Hi it was interesting to me. It would appreciate if you could give me more
    details.
    The method will be same as other hydroponic veggie?
    Thank you?

    Hello, First year with DWC is done :DDD Can’t wait for next one 🙂 Please
    tell me sth about your fertilizer, or better, the NPK ratio. ?

    Thanks for showing this.. especially how to mitigate the root rot.. Most
    people will have plenty of problems with Root Rot.. You may want to try
    some Trichoderma Spores in the early stages of your growing to protect your
    roots from infection.?

    The only veggie I grow inside is lettuce,because of Global warming,has made
    Florida direct sunlight over 100 degrees Fahrenheit,which kills,lettuce and
    deforms the lettuce that doesn’t die.I will try some hydroponic
    lettuce.”Early Girl” was the best hydro lettuce I ever tasted.?

    yes the crop looks good! Just going through your comments and to recap for
    us novices…

    1) What are the strings for…How to you set up the pots for a growing vine?
    2) What is the best additive/growing medium for taste?
    3) What/how much sunlight can the plants stand?
    I rent, can’t dig up the backyard so Hydroponics is the way to go. Backyard
    is direct sunlight. Garage has no sunlight and growing inside is out of the
    question.I can erect a tarp but will have to set up/tear down daily.?

    the question is…..how did they taste? Did they have a rich earthy mineral
    taste? If not, you might want to try adding rockdust and sea-90 to the
    mix. ?

    Perhaps the issue with your Kratky setup is that the technique was
    developed for use with specifically hydroponic fertilizers, not organic
    compost teas and such. Potassium, needed by tomatoes in good quantities,
    are apparently hard to supply via earthworm castings, compost, etc. Some
    micronutrients could also be an issue. You’ve seen the tomato monsters
    Bobby, mhpgardener, grows…but his is not trying to use purely organic
    nutrients.

    The other thing is that the Kratky method was primarily developed for
    short-grow crops like lettuce, where the reservoir never needs to be
    refilled. By the time the nutrient level drops to near-zero, the crop is
    done, ready to harvest. But, for long-growth crops, the nutrient level
    needs to be replenished…and the higher level solution could now drown the
    roots that adapted to be in the air. My gut feeling is that the level
    should only be raised by a few inches once it’s dropped to near the bottom
    of the reservoir OR an air-stone should be added if raising the liquid back
    up more than that…sort of a hybrid Kratky-DWC setup.

    As for size…personally, a quarter pound tomato is just fine. With larger
    ones, we tend to cut them, not use all of the tomato, and then what? Let it
    sit half-used in the fridge? Better to have smaller ones and use the entire
    fruit every time you cut one open. Plus, some of the best disease-resistant
    types are bred to supply 4 oz fruits, and that’s fine with me.?

    Hi Larry, nice update lots of tomatoes you grew. What kind of plants are
    they? My celebrity grew ok in the gutter system, but I did not get lots of
    tomatoes.
