If you think being around to water your plants might be a problem, then a DIY Auto Watering System might be what you need to solve it. With the correct setup, you can fill a reservoir with nutrients, and then be assured your cannabis plants will be watered automatically.
This can be great if you work away from home throughout the week. If you only come home from work on the weekends and want to grow weed, or maybe you have a holiday or vacation coming soon and you won’t be around to water your plants.
An auto watering system for your weed plants is easy to set up, cheap, and makes the whole process of feeding your cannabis plants a lot easier.
Buying an Auto Watering System for your Grow Room
You can buy an auto watering system for your grow room from Ebay or Amazon for a decent price. However the problem is, sometimes these may not be adequate for your grow room.
For the best result and for a better price, you should build your own DIY Auto Watering System so it is more suitable to your grow room
I have used a set up bought from Ebay in the past. and I ended up needing to build my own Watering System as it wasn’t adequate enough for growing four weed plants.
I decided I needed to get a Watering System that was more capable.
This year as the season gets ready to start. I have decided it’s time to either build my own setup, or possibly lose my plants. So after a little trial and error, the resulting set up will pump 1.6l in 60 seconds per ring. For the most part this is the amount that I hand water, and therefore the plants should be much happier.
Controlling DIY Watering Systems
So for the build I decided to use a digital timer. This allows me the ability to program the system for 1 min intervals and also select the days of operation. .
Constructing the system drip rings
The drip rings will be used to deliver water to the surface of the soil.
First I began by cutting off 4 lengths of tubing 24″ a piece, Then using 4 “T” fittings I constructed 4 Drip rings.
Next I drilled holes in the drip rings to deliver the water to the soil. To do this I decided on using a 5/64th drill bit. Then I decided to start with 2 holes in the ring and work up to more if necessary.
After testing they ended up with 3 holes.
Pumps For DIY Watering System
I will be using a fountain pump to provide the needed flow of water to the drip rings.
The pump I have is capable of flowing 320 GPH, a much smaller pump would be better suited for this purpose.
Adjusting system flow
The pump I used has an adjustable inlet, which is useful for tuning the flow rate of the DIY Auto Watering System. Opening and closing the inlet allows for adjustment of the rate of flow, Thus allowing you to fine tune the auto watering system to meet your needs.
Final Assembly of the DIY Auto Watering System
I started out by placing my buckets in position and then placing the pump in the reservoir.
next I cut several pieces of tubing to fit and connected all the drip rings to the pump.
Make sure all fittings are firmly attached, the last thing you want is water spraying all over place or possibly contacting electrical devices.
Now your DIY Auto Watering System is ready to test.
Time to test out the DIY Auto Watering System
Once I plugged the pump into my Digital timer and programmed it for 60 seconds, I was ready to test the flow rate of the DIY Auto Watering System.
Once the cycle was complete, I could now measure the amount of liquid. I ended up running the system 4 times to ensure accurate measurements.
Measuring the final system flow
To measure the flow rate I emptied the contents of a single bucket into a measuring cup.
I measured each bucket separately, In order to determine the individual flow rate.
The results were approximately 1.6l of water per drip ring.
Since this is close to the amount that I use for hand watering no further testing was required.
And my DIY Auto Watering System is ready for operation.
I hope this helps anyone in a similar watering situation
I now feel confidant that my plants will be properly watered while I am away working this season. And feel that it may also work good with my scrog, where it can be difficult to reach the plants in the back.
Now I need to find a bigger reservoir Happy Growing
