B.A. Kratky DIY Indoor Garden Containers and Window Gardening

DIY Indoor Hydroponic Garden Containers and Window Gardening – Enjoy container gardening? Create styled garden containers and by using the Kratky Hydroponic Method, learn how to grow dirt-free with this short tutorial on using jars, spray paint, and simple grow techniques. No grow light needed, just a bright sunny window sill was all the light that these hot pepper plants needed. Perfect way to get ripe pepper pods indoors or to start plants early and have hot peppers before anyone else in your neighborhood. Tested with peppers, tomatoes, squash, cucumbers, passion fruit, bok choy, and other plants. Very low cost and beginner level project, the containers easily compliment most interiors including home and office. The growing method used often goes by the name of simplified hydroponics, passive hydroponics, Kratky method hydroponics, and was originally referenced by William F. Gericke in 1929. Google search for “mason jar hydroponics” to see examples. This type of gardening is also great for crafters and school classrooms.

    I was surprised at how well the plants did with just window light.

    I’ve made pots exactly like this for a while and they are very low maintanence fore plants that are not heavy drinkers. For thirsty plants in south facing windows in summer I’m experimenting with floating innerpots in wide and very high outerpots. It works great but I haven’t figured out how to support tall plants.
    The downside with this setup is replanting growing plants in netcups. It’s a hassel. Also dropping waterlevel in strong sunshine will dry out the roots. The black primerpaint and a big volume of water is important unless you place it in low sunlight.
    Making small versions of these for small plants only work in low sunlight. I’ve tried. Unless you water them evry other day, but thats not my way.
    Some plants only drink the fertilizer but not much water so even if you don’t need to top off the water you sometimes need to add more nutrition.
