only one over flow pipe
re: confused about 11plant13html
its a bad drawing. there is only one over flow pipe which in the picture is crossing blue water with the horizontal feeder pipe- it should be broken in diagram cause it does not reconnect with the feeder pipe. the feeder pipe should also be broken at its end to show that it could extend to other bottles.
i think im going to make something similar without the cut off two liter bottle. in its place could go a plastic sack (filled with 10 liters perlite) supported by a thin wire upside down lampshade type thing and sealed around a tube extending from the tee with a rubber band. a screen would have to be stuck in the extension tube and pea gravel laid on top of perlite. What can you grow in a cut off two liter bottle? a head of lettuce?
Yes Lettuce
