Soil Watering with an IV Bag

Howdy Farmers

I built a box to grow outside year round and ran into some challenges with my design. In coming up with a solution to my watering issues I found a product called ‘Smart Bottle’. Basically an IV bag that comes in 1, 2.3 & 5.6 gallon sizes.

I added a few parts and came up with a gravity feed watering system that makes watering very easy. I can control the flow with the valve and water precisely where needed. The bags below are the 1 gallon size.

Thought maybe this could help others with similar challenges.


I use sub-irrigated planters in the garden for flowers and herbs. I thought I would try a smaller version on some cannabis


I like this idea. Just a 2"pvc? Holes all thru? How does the water get all around with just a single pipe? Would it not moisten its surrounding area and drain thru?

This is one of the bottom’s of the inside bucket. I used a length of perforated drain pipe to set the depth of the bucket. The holes is the bottom of the yogurt container lets water into the wicking chamber. The small holes are for drainage and air. The large one is for the 1" pvc water tube.

This unnecessary. I put hydroton balls in the bottom of the container.

I used a piece of landscape fabric to keep the soil from falling through holes and filling the water reservoir area.
You pack the medium into the container which sits in the water. It literally wicks the water up into the medium. I used a high porosity peat mix in these. They are ready to receive the transplants

Here is another variation. This one is a 4 gallon nursery pot inside a 5 gallon bucket. I lined the nursery pot with landscape fabric so it would act as a wick. I did it this way rather than using a separate container.

I transplanted into it on 4/8 and did my LST

Here she is three weeks later on day 72 . She is happy. I have her under low watt veg lights. I am trying to keep her small until I have space to grow her out. She is in coco. All are being fed Jack’s.
Just having fun trying some new ways
