A few days back , making rainfall barrels out of re - purposed 50 - gallon pickle cask was all the rage . While there is nothing faulty with doing that , I was never tempted . I think they were unattractive and , worse , held too little water supply .
By summer , a vegetable bottom demand about 1 gallon of water per square foot every week . Watering a unmarried 4 - by-12 - foot veggie bed would drain a mess barrel , and then you ’re out of urine until it rains again — unless you set up a whole series of hole cask .
And lining up more of them does n’t make them less worthless , and itmultiplies your toll of connexion and the time to install them .
expect around to see if anyone had a undecomposed choice head me to IBCs : Intermediate Bulk Containers . you could find them advertise on Craigslist for $ 75 to $ 150 apiece ( and they are well worth it ) . I calculate that if it take for more Imperial gallon than it be in dollars , you ’re mother a sound deal .
And an IBC holds 275 gallons — more than five hole barrels ’ worth , but with a smaller footmark and requiring less hardware .
An IBC is a 48 - by-48 - by-40 - inch cube of food - ground level charge plate mount up on a pallet . It makes me think of the Grateful Dead call “ Box of Rain . ” An aluminum cage keeps the moldable cube from collapsing . At the top is an 8 - inch - wide screw - on lid . Near the bottom is a 2 - inch spigot .

The ones I ’ve purchase still had the faint scent of the almond oil they originally check .
To keep alga from rise indoors , I slap on a twosome coats of dark browned paint made for charge plate . Then it looks like a three-dimensional Hershey ’s Kiss . Plus , I install them in a way that they can send water acclivitous to the garden without a ticker .
Here are 6 ways to maximize pelting water in your garden .

Connect to the Downspout
There are two elbow room to get rainwater into your gun barrel : under an exist downspout and not under a downspout .
Under an existing downspout
dilute a pickle in the top of the barrel , and send away in a downspout . utilize a section of downspout to distinguish an outline on the top of the gun barrel . bore a hole just inside the line . Insertthe blade of your jigsaw into the golf hole .
Cut along the line , and your downspout should fit snugly through the maw . You ’ll need to add the same kind of overflow hose near the top of the barrel that any pickle cask or store - bought pelting barrel would have to handle excess rainwater .
Not under a downspout
I recommend using thedownspout diverter sell in the Gardener ’s Supply catalog . It ’s a metal box that fits into the downspout , diverting piddle into a hose that connect to yourrain gun barrel . Install it correctly ( meaning that , even if you ’re a humanity , you take and surveil the directions that come with it ) and you wo n’t need to mess up with an outpouring hose .
When the gun barrel is full , the rain will back up in the hosepipe and go down the downspout . Installing it aright means that the inlet to the barrel is at the same height or low than the diverter .
If you require to set up your barrel far from the downspout than the Gardener ’s Supply hose would allow , bribe a3⁄4 - inch credit card hose used in Netafim drip irrigation systems . These are often sold at bragging - box seat memory board .

Build a Base
Your IBC will amount with one pallet . It works best stacked on several more pallets so you’re able to rig a bucket under the spigot and station water rising ( more on that after ) . Get free pallets from feed - and - seed stores , garden centers , HVAC contractors , big - box stores , etc .
If they have “ HT ” pigeonhole on the side , they have been heat - deal and do n’t have chemicals in them . Most pallets that have been regale with chemicals have brilliant pigment slapped on the side and are expensive , so stores send those back for credit .
Unless it ’s plastic or metal , get rid of the pallet from the bottom of the IBC . Add it to your pallet deal .
Once you have all the pallet you need , conjure up them off the soil by putting a cinder block under each box . brick or scraps of pressure - treated baseball bat will work exquisitely , too . The main thing is to get the pallet Sir Henry Wood on a rot - proof fundament at least 5 inches above the terra firma so it wo n’t decompose .
Level up the foundation pieces , then start stacking palette . weight unit and friction will keep the palette from moving around , so no pauperism to have intercourse them down . Check that the pallets are unwavering or pretty skinny to it .
Then , wrap the pallet and foundation with some fence telegram to keep critters from making a plate under your IBC . draw out the fencing as an forestage on the groundaround the basis to keep critters from digging their way under the pallets .
Last , employ something waterproofed and UV - proof as a matte ceiling to keep the pallet teetotal : scraps of pond liner , roll roofing , scraps of metallic element roofing , etc . Most tarps wo n’t stick out up to the sun ’s UV radioactivity , so do n’t go that path .
I had just enough scraps of press - process lattice , so I used them to cover the side of the pallet stack , to keep critter out and to make it look a little more like a garden feature article , but that ’s not necessary .
Once your pallet stack has a cap , foundation and critter - proofing , put the empty IBC on top . It should be light enough for one or two people to lift into position . No need to screw it down . forgetful of a tornado , its weight will keep it in place .
keep up water by capturing and using rain urine on farm plants .
Let Water Flow
Some people unscrew the 2 - in faucet and use wad of PVC adapters to dial down the diam so that a organization spigot can replace it . I hear that once and found that the adapters seriously constricted the pace of flow .
I also miss have a big tap that could fill a 5 - gal bucketful or a 2 - Imperial gallon lachrymation can in a matter of seconds . So I keep the 2 - in spigot in place and make a level area under it with bricks where I can set a bucketful or watering can and take it quickly .
To water my garden with a pelter hose , I attach a brass spigot near the bottom of the cube . To do this , I use a drill and a spade act that cuts the same diameter as the inside diam of the thread of the spigot . That way the tabu edge of the threads will bite into the charge plate as I chicane it into place .
Just before it ’s have a go at it all the way in , I apply a beading of exterior course caulk around the duds and then screw it in the last bit . lead the caulk to heal for 24 hours before moving anything or get pee into the cube .
Send Water Uphill
Here ’s the sport part . I had a good situation for my IBC , but the garden was rising from there . Carrying water by paw was out . Installing a pump and rootle electricity was expensive , and pump like to break down anyway .
This was one of those consequence where I feel like I memorize everything I need to sleep together in mediate shoal skill class . I remembered teach that water will run uphill through a hosiery if the inlet is kick upstairs up higher than the retail store . This is the same principle that gets water from a city piss pillar to your house .
That ’s when I realized that if I stack the palette just a tiny bit in high spirits than the high-pitched point of the garden , gravity would push the water uphill into the garden .
Pallets are about 5 - inch tall and I had some 6 - by-6 combat for a founding . In this casing , six palette put the spigot of the box just above the hosepipe issue at the high dot of the garden . The rain would flow uphill .
From the gun barrel to the high point , I would use a garden hose . From there , a soaker hosepipe express water downhill . ( A soaker hosiery extend acclivitous loses most of its water right away.)Animaflora PicsStock / Shutterstock
Maintenance
Your super rain barrel should be sustentation - free mostly . exit the spigot when it ’s empty so it will replenish during rains . Come winter , start the spigot so waterdoesn’t freeze inside .
Depending on condition , you may have to touch up the rouge periodically to keep algae out of the urine . Keep an center out for critters setting up house in the palette stack if your fencing is n’t tight enough .
Keep your rainwater gutters free of farewell in the fall and oak prime in the spring . ( Hopefully you ’re doing that already . ) And then enjoy tons of free body of water from your box of rain .
