In my bid to promote self watering of my tomatoes I have filled a
couple of empty milk bottles, made a hole with a heated NEEDLE (so
we are talking about a tiny hole) underneath hoping that the water

the tomato plant...


The 6 pints bottle was empty after about three hours! What have I
done wrong? I did leave the lid on. Other suggestions?

You could try running a cotton string down from the bottle (down to
the bottom) to the soil (buryed a bit). Water would wick down the
string. Increase the string diameter to increase the water flow, and
vice-versa.

Or, you could try using a commercial drip irrigation "dripper" and
the appropriate tube coming out of the bottom of the bottle (or,
maybe even siphoning from the top) and see how that works. You might
have to raise the bottle to get enough pressure.


I was going to suggest the drip irrigation dripper myself. I have set
up gravity feed sustems with them in the past and you get a regulated
flow. One problem is that they usually work off a timer and run about
0.5 to 3 GPH, so too much without the timer.

With gravity feed pressures, they may work fine.
