So I have 2-liter soda bottles. I stuck a syringe needle (26 gauge to be exact) into the base of it, and now the water is slowly dripping through the needle. I can adjust the drip speed by tightening or loosening the bottle cap.

My plan is just to plop the 2-liter bottles somewhere next to my plants so the dripping goes to the soil.

One problem is that the needle only extends ~1/2" from the bottom of the soda bottle. I don't have enough room on my pots to stand a soda bottle on, so the dripping prob will have to be somewhere off to the side of the stem (not centered).

Hope that sums it up...It seems to be dripping alright, I just don't know if I trust it to last 8 days (I don't know at all how many day's it'll last!). I don't have much time to optimize drip rate...
