We had a lot of trouble with the bicycle needle airlift (although it’s working well now), but this seems really simple so I’ll be trying it for our next column. Thanks a million!

Place your pump higher than the reservoir and there’s no need for a one-way valve. You should never place an air-pump below the water line. Like Janet said, the water pressure might be too great for an air-check valve to handle, giving you a false sense of security. Actually, most cheap aquarium pumps have a [...]

What I’m thinking of doing is using Starbucks tall-sized plastic cups and drilling holes in them to use as net cups. What do you guys think?

I like all these innovative ways of mounting! I got a question though. Since we are using a tube to guide the water down into the next pot, why don’t we just completely cut off the top half of the bottle and use the bottom as a container funnel? Won’t that allow more air for [...]

@Tim, btw did you use net pots? I’m contemplating not to but experience of some others said the roots ended up clogging the bottle cap.

Or rather, what the t-joint is is an aerator that mixes air with water. Air comes in from one inlet and water in the other. So even if the air is continuous, like from a gas canister, if the pressure of the water inlet is comparable to the air, I’m sure they will mix up [...]
