The Good Eye and Willy Bag Seed: I think the problems with our Aerogardens, (A/G's), depends a lot on how we're using them. I use mine for everything, from planting seeds and growing clear up to harvest. I've also cloned in my A/G's but I found a: cloning tray, rock wool cubes and humidity dome were a lot more efficient, (50 clones instead of 7, 17 or 21 if I put all three to work).
Admittedly, if you're only using your A/G for seed propagation or cloning, you're less likely to have a roots in the pump issue because there's not that many roots to contend with. But if you're growing a couple of plants to harvest, from around the vegging stage on you have a potential for the roots getting into the pump and ruining it. I was told about putting a woman's nylon sock over the pump and tower assembly to protect the pump by a customer service rep at A/G.
And it's not the freebie socks they give the women to try on shoes that I'm talking about. Those are pretty course socks the nylon socks I'm talking about are very sheer. The nylon socks I'm referring to are sold at Walmart for less than $2 a pair. You'll find them in the women's department near the shoes. A pair are packaged in a small clear plastic ball with a flattened end that has a label. The ones I use are: "Queen size," "Knee Hi Sandlefoot," nylon socks. Their bar code on the label is: 04741780824 and they come in a variety of colors, although I don't know why that would be important. Ask your: mom, girlfriend or wife. They'll probably have an extra you can try. Just stretch it over the tower and pump very carefully. HSA
