Yes. They can and are used to automatically water your bagged or cut Christmas trees automatically. Place the rock on a box or shelf so the rock is higher than where you want the drip to go. Make sure the lines are secured so they do not leak. Fill the rock, set the dripper and it will release water slowly to the desired container. Check at first to make sure the drip is not so fast it overflows the container.
In the past I have made concrete rocks in the 1 gallon and 2 gallon size. I can
still make these as a special order but they are heavy and more fragile.
We have also made” rock pots “out of concrete which are still popular where
I do not have to ship. There are pics on this web site of all.
We are a growing company and would like to make a 25Gallon plastic rock
as soon as cash flow allows.
There are a couple of ways to approach this and I am not sure exactly where in
the system you would want the timer , but here are some suggestions.
1. There are shut off valves for the 1/4″ line sold . They could be placed at the
main source ( maybe 3-4inches away from where it connects to the rock) which
would shut off all drippers.
or place shut off valves in line right before the drippers to control each dripper.
2. I cannot find 1/4″ timers so far. But I did find under ” irrigation timers” on
searches a few that could be worked with but adapters would have to be used to
reduce to the 1/4″ line and I am not sure if that would affect the flow.
Right now I have no easy solution for this.
Yes I have successfully done this myself. There are a few different ways to
1. You can run run a line from an existing drip or sprinkler line to hole in the
back of the rock. Depending on how long your drippers or sprinkler timers
are set you must attach say a 1gallon/hour or 2gallon/hour dripper tom
reduce the flow of water into the rock. For instance, if you run your sprinkler for
30 minutes with a 1gallon/hour dripper you will fill 1/2 gallon in rock.
2.There are also hose timers that could be attached to an outlet and
then run the hose to the hole in the back of the rock to automatically fill it.
Sorry to say they will not. People have told me though that they put their
rock on a chair or ledge and let the lines flow down to their potted and
hanging plants while on vacation.
When you first put water in your rock it may take a short time to get flowing.
I recommend opening some drippers all the way to prime the rock and get
the air out of the lines. Then replace the dripper caps and adjust as you like.
The threaded barb on the back of the rock is made to fit tight to prevent leaking.
It is best to very carefully tighten the barb till the threads are almost dissappeared.
Thr barbs are tough but are plastic and can break , which is why I package 2 with
every rock. The biggest reason to tighten this far is that it strengthens the barb.
The threads of the barb can act as weak points when the attached lines
pull on the barb.
Make sure the rock is completely drained of water. If you open the drippers
and blow on the fill hole on the top back of the rock it will push water
out of the lines. Although the rocks are made of durable plastic it is probably
best to take them inside if you expect severe winter weather.
Yes you can. But, I would recommend a liquid fertilizer to make sure it
mixes well with the water and does not leave risiduals that may clog the lines.
Yes you can. If the 1/4″ line should become plugged
you can use a coat hanger or something similar to unplug.
I place a hole in the dirt next to the plant and have the dripper flow
into the hole for deep irrigation. This really helps on those very hot summer days.
If you want the drip to last longer turn the drippers down to a slow drip.
I have also noted that it is best to set the dripper
flow a little faster than what you want as the flow slows over time.
