Swiss Chard

tampahydroMay 7, 2009

Wondering if anyone has experience growing swiss chard hydroponically. I am having trouble finding information online, but im sure someone could offer advice.

First off, I am wondering what the ideal nutrient solution is. I have also read they are able to tolerate partial shade, but is that actually preferable this time of year in Tampa, FL?

I should add that I am growing them in a static flood and drain perlite system grown outside.

What would the ideal pot size be? I was thinking quart to 1/2 gallon size.

Swiss Chard: pH 6.5 - 6.8 (growth stops @ pH's N 200ppm
P 50ppm
K 160ppm
Ca 260ppm
Mg 40 ppm
S 50ppm
EC: ±2000µS max (tend to grow better at lower EC's)

½ gallon pots are OK. They can take partial shade. In fact - here in Africa - they suffer a bit from the midday

Have fun

I am growing it presently in an ebb and flow system under glass. The TDS is 1370 and the pH is 6.5. I am using four inch pots and there are fifteen pots in a 3 square foot system. There is a photo on my blog.

They look yummy jackfrost.

I'v tried Swiss Chard in DWC, but the roots are thin, frail and sensitive. The plants don't like them moved around, so it was a disaster. Ebb&Flow seems the best.
I didn't have much luck with 2000µS. Seems to be too strong.

I tried DWC also. I had a few extra plants and stuck them in an ebb and flow. They did so much better in the ebb and flow I have not used DWC for chard since. I had some for dinner last night. It is excellent, tender and tasty. The TDS I am using is about right for my system. I am also going to try beet greens in the ebb and flow. The chard does not seem to mind the heat, but I do use a shade cloth to block the midday sun.
