Rainbow Swiss Chard

Note, Trying to sprout under grow lights ... success with all other Victory Seeds I've tried, nasturtiums and lettuces popped their little heads up after only 3-4 days... amazing, but well over a month later, I only had one rainbow chard seed ever come up. What am I doing wrong... suggestions anyone?

I have had no trouble with diseases or pests on the chard, except for a couple caterpillars. They are right next to pepper plants that were attacked by leaf-miners, but they do not seem to have had any effect on the chard. I have about six plants planted in the backyard. Since mature chard is a little on the bitter side for me, I usually harvest it when it is still fairly young, maybe four to five inches in length. Beautiful colors, although the plants that we have planted only produce about 1/3 of the greens my boyfriend and I use. The New Zealand spinach I also purchased from here has given more.

Chard couldn't get much better than the rainbow chard. I don't grow anything to just be a ornamental plant so I love nutrient dense foods with beautiful foliage. It tastes great too. And I have gotten kids who are picky eaters to try it due to the new colors they can explore!
