Flow to waste is also known as drain to waste in the hydroponic world. I implemented this method right after starting the no-weed garden a few months back. It was to provide a little bit of hydroponic nutrient to the outside containers. What I learned was that it was so much easier and very consistent. In my research, I found out that this methodology already existed as a form of Drip Hydroponic Systems only there’s no recirculating nutrient. Now, they way I’m doing it is still yet a bit different. Here’s how it works: 1. House water fills up to 250 gallons of storage barrels two times a day via a timed Orbit watering valve. That water off-gasses the chlorine and gravity feeds a “Distribution” barrel via a float valve. 2. A nutrient tank is mixed with 50 gallons of super-concentrated nutrients. A timer sends a small amount of that to add to the distribution tank after every watering of the greenhouse. So after, every watering cycle, water from the storage barrels and concentrated nutrient fill in the distribution barrel at the same time and is mixed with a double-bubbler (fish air pump with 2 air stones). 3. Any excess drainage from all the containers in the greenhouse flows back to a “waste” tank where it is re-used for the outside containers. Ideally, you want to minimize excess drainage. The waste tank also is fed from the storage barrels with regular water to ensure the pump never runs dry and that the outside containers always get watered. 4. Everything is timed for 2 times a day and can be changed from 1 to as many timings per day as desired. The simplest version of flow to waste is add nutrient-water to a container and let the drainage drain anywhere else […]

    I bet you are going through some Master Blend and Calcium. Morgan County must love you and Chuck from Fensterfarm. Great video. TFS Lisa

    Just a little note to add for dummies like me, make sure the Epsom salt does not have perfumes or dyes added. They sell it both ways.

    Brent I think you said thourally enough. Best wishes Bob.

  • Hi Brent, love your channel mate and love the new setup with the flow to waste, I think it will definitely save you a lot of your valuable time. Just be careful with the concentrate mix as calcium may precipitate out of of the solution in a few days, hopefully the bubbler prevents this.

    To save you more time, you could look at mixing a 100X concentrate of your masterblend + magnesium sulfate in one container and another 100X concentrate of your calcium nitrate in another (you'll need clean/rain/RO water for the mix) and use a couple of venturi irrigation mixer/injectors + adjustors between your water supply and your nutrient tank to manage the final EC in your nutrient tank. This will allow you to remove one of your pump/timer combos and the venturi mixers are simple, reliable and cheap.

    To save you even more time :), you could get rid of the water supply tanks and the main nutrient tanks and feed your plants with the main line from the house + the 100X concentrates tanks + venturi irrigation mixers 🙂

    Looking forward to part 2 and your progress with the hydro, have a great day my friend. Cheers, sumo.
