Hair dye application bottles from any beauty supply store. They have a very small hole and a pointed nozzle so they drip very slowly.

I can fill my bottle with water, stick it into the soil and it will gradually drip water directly into the soil near the roots. I would estimate they dribble a drop of water every 10-20 seconds but it does vary depending on the angle, obstruction of the nozzle, and other factors.

It has been working very well so far on several sprouts and I hope to use it in the long run.

These bottles hold 6 ounces and are about $2.00 each.

A downside is if you fill the bottle with the full 6 oz. of water for a seedling or a sprout you could potentially flood the pot. Most of the bottles I have used drip very slowly and the evaporation from heat, air and use by the plant keep a nice balance going.

Cheers.

Just an update. I used this method the other day when I was out for 20 hours. I filled my bottle with 2 oz of water, then set em up and they kept my plants watered and happy the entire time I was gone. I also put an oz of nutrient mix in there and they get fed. I, so far, swear by color applicators for young plants. Not sure how it will do when they grow up but for now, they are awesome.

you could also just water the soil once a day. There is no point if you have to refill it every day anyway.

I do water daily. It's more for when I am gone for long periods of time, hence why I said 20 hours. If I water it all at once it dries faster, if it drips slowly, it stays moist longer. This way I can be gone for a day or more and keep things healthy.

smart thinking but i would worrie about the chamicals in the bottle from the hair die but i'm sure you washed and bleached them out

Of course, I bought unused bottles.

its a good idea, but 20 hours isnt long for a plant. some people water every few days when the soil dries out, others, like me, water once a day. it doesnt need to be overcomplicated by watering all day like that. now if you put it in a drip feeding coco bucket with a run off res, then thats a different story.

Yea, like I said its not for everyday. The last thing I'd want is flooded pots from watering all day. Didn't I say that already? I swear its like you aren't even reading anything I am writing.

i thought daily meant every day.

Yea, I debated the title of the thread, so I put (or less) in the title.
