  1. Right Luke! Most leafy green edibles DO NOT NEED massive depth to grow! Most of them would happily grow in just 6" to 8" inches! ..Many of the vertical growing containers..have pretty much proven that. We really want the plant to focus on growing the vegetation.. not a massive root system. We also see hydroponic systems grow many leafy green edibles in fairly shallow (4" to 6") depth systems… So.. we waste a lot of space and material in many situations..

  2. This video reminds me of a thing I always wondered doing container garderning, that is whether it is better to plant say 3 tomato plants in 3 seperate 10 gal containers, or 3 tomatoes in a single 30 gal container.

    My thinking is that planting in the 30 gal container, all 3 tomato plants each can potentially have access to the whole 30 gallons, with their roots intertwining. Or is really just the same in the end, as they will end up competing with one another, with 3 times the ressources but 3 times the competition?

  3. 3 gallon of soil for tomatoes, are you growing dwarf/micro tomato? Then yes a 3 gallon should work fine BUT if your growing a determinate tomato you should be in a 7 gallon or bigger and if your growing indeterminate tomatoes you want to be in no less than 20 gallon range if not bigger so that you do not restrict root growth.

    Now for peppers you want 5 gallons or better.

    It pay to read studies done on vegetables….

    A study done in Ithaca, N.Y. showed that tomatoes they grew had a root depth of 3 feet and a lateral spread of from 3 to 4 feet.

    That's 27 cu ft or 173.57 gallon of soil one tomato root structure took up.

  4. A 1020 tray is about 500 cubic inches, so its around 2.1 gallon of soil. So I could easily plant 2 head of lettuce in a 1020 tray. Ill give it a try !

  5. I’m growing a climbing Nasturtium, just waiting for the seeds to germinate. I want them to go up my side wall but there’s no soil at the bottom of it, just concrete, so I guess a containers the way to go, or a wall fixed container of some kind, but I don’t know what depth they want. The other regular Nasturtiums I have growing I have noticed that their roots are long enough quite honestly, only they’re still only a few weeks old so I’m not sure how much longer they’ll get, so for my climbing types I guess it’s just trial n error, because I don’t know how deep they want to go, and that’s one of the more confusing aspects for me when it comes to gardening.

  6. Thank you for this video! I'm just starting to grow vegetables and herbs and I'm building my own low budget raised garden beds and boxes and containers so this info is really helpful <3

  7. We are in the foothills of northern California, so we have very hot, dry summers, but our property is also in a little micro-climate that can dip into the single digits in winter, so I'm just starting a greenhouse. Just wondering what soil mix works best with vegetables in the shallow beds for lettuce, tomatoes (want to do hanging baskets for the tomatoes), peppers, etc., that will keep them well-nourished and thriving? Also what sort of fertilizer are you using? Liquid?

  8. I am so glad I found this informative video. This is my second year of growing my own veg.last year crop was really good so i want to extend it all with these foldable grow bags etc.

  9. I came here because I planted many seeds in what I'm starting to believe to be far too shallow of pots, since all the seedlings did great at first but now are dying fast.

  10. Ty for yr explanation so i can top up more soil to my veggie pl cuz i keep adding new stem cut so i feel their roots r v saturated n running out of space for soil
