New to gardening in general let alone hydroponic gardening.
I had OK success with my first 6 pods for 260+ days, and just cleaned it and refilled it and started fresh with 6 chili pepper pods.
Unfortunately, I didn't have the sense to plug the pump back in (smh), and so it went 5 days with no glorious pumping action.
The pods seem to be developing little bit of white fibrous material (mould?) right on the centres. I used tweezers to pull it off as best I could but wondering if the pods are now doomed because of that stupid mistake.
I have done that several times. Forgetting to plug the pump in. Your plants should be fine. As for the white fuzz, AG states it is fine. You can find the reference in this thread, first post.
As for the peroxide, that was a tip I received from an AG rep a long time ago. if you do use, make sure the qtip is not soaked to the point of dripping. You just want to dab it around the plant on the sponge, not the plant itself. Some believe in this practice while others do not. Gently removing it with a plain qtip or even a toothpick is fine as well.
Please keep us posted on your progress and post some pictures as it grows too!
