Back in January, EG from Our Engineered Garden shared yet another one of his awesome creations--a self watering planter (or a self watering container; SWP or SWC). I instantly loved the construction of these SWPs because of the fact that they use recycled/inexpensive items, and each container only uses one bucket instead of the traditional "bucket in a bucket" method (you can find instructions for that method here and here).
Last year I received a bunch of kitty litter buckets from a very generous Freecycler, and planned on making SWPs with them but never got around to it. Frankly, I'm glad I didn't because I have a better understanding of how things will grow in my garden, and can now make more using EG's method.
I bought a couple floor tile squares at HD for $.65, and blew through those while doing a few trials of cutting incorrectly and drilling holes that were too big. I later found $.45 tiles at Lowes.
My redneck work area in the garage...
We don't have a tool bench or a table top that I could get all crazy on with the exacto knife, so I used cardboard LOL. And, nooo, I won't be spray painting my containers gold... When I traced the yogurt cups for the wicking basket hole, it was way too big (or small depending on the side traced). The top to the spray can was a much better fit.
The tools...
I've used a hack saw for previous PVC cutting projects, but after someone at Lowe's cut my 9ft PVC pipe in half by squeezing a pipe cutter 3 times and after I picked my jaw up off the floor, I came home with one. I love this tool! I'm not strong enough to get a good back & forth motion going through PVC so it's always a pain to do. The pipe cutter was still hard to use. Actually, I ended up setting it up on the ground and stepping on it HA! (Not shown is whatever tool or bit DH will let me use to cut the holes in the lids.)
Because of the smaller width of the bucket, the yogurt cups overlapped the wicking basket hole/area.
Overlapping solution: cut the top sections of the containers.
Tada!
I will be using kabob sticks stuck in wine corks as my water level indicators.
I can't wait to see how growing bush cucumbers, baby bell and white habanero peppers in my SWPs will turn out!
Lastly, this week EG showed us how he is implementing his SWP concept with a large storage tote. Perfect timing, since I brought home these 18 gallon lime green totes (what? they were on sale!) two weeks ago! Now I can make two. Yeessss...
Thanks for sharing your brilliance with us, EG!

You did it! Perfect. I hope they work just as well for you as they do for EG.
ReplyDeleteExcellent! I hope they work just as well for you as they do for EG.
ReplyDeleteI'm glad that you found the information useful. That's one of the biggest reasons I blog - to share concepts and experiences with others. The peppers will work great in them, but i've never tried cucumbers in one. Let me know how they do.....
ReplyDeleteYou go girl! How are you liking our spring? weather. We went from Winter right into early Summer in a week. You gotta love Calif.
ReplyDeleteEG~Thanks again! I'll be growing Renee's Bush Slicer cucumber which is *suposed* to grow about 3ft tall, even though it's an indeterminate plant. If my peas taught me anything, it's to expect at least an additional foot. I have a feeling I'll need to water every day at peak growth...
ReplyDeleteLiisa~Back east it usually goes from winter to humid, so I'm loving every moment of it! There's nothing better than having the windows open with a gentle breeze rolling down off the hills. *sigh*
ReplyDeleteLooks pretty good! And I'm with you with the low-humidity stuff. When I go back east to visit, I nearly wilt.
ReplyDeleteHey Momma - I love your kitty litter SWC! I have been wanting to do this forever. I read EG's tutorial and now I'm reading yours... i feel like I could **almost** do it. I just don't get the wicking cup. That's what's losing me. I suppose the other yogurt cups face DOWN? right? and the wicking cup faces UP? Ugh - I'm just lost on what the upward facing center cup is for?
ReplyDeleteKate~Thanks for checking out my blog! You bring a lot of inspiration to me through yours, so I feel honored to have you here!
ReplyDeleteFor the yogurt cups, they all face up, and each has a whole cut in the bottom/side so they fill up with water (more water storage). The actual wicking cup has a small whole in the bottom (maybe so water flows in slower?), and is filled with the growing medium before the landscape fabric is placed over it and the tile (I don't believe EG mentioned this in his tutorial but did later in a comment--good thing or I would've left it empty). The growing medium in the cup acts as the wicking agent. EG mentions the growing medium in the cup creates "capillarety," but I think that begins to go beyond my brain power. ha!
Thanks Momma! I'm one of those silent readers - i do visit from time to time and always mean to comment and always forget... no excuses.
ReplyDeleteSo the yogurt cups face up? And have a hole in them at the bottom? and the middle one has the compost added to it BEFORE you put the landscape cloth on top of it? GAH! I have so much to learn about these... Thanks for the tips though and capillarety sounds like it's related to blood to me - LOL
Looking good! I really need to get on the ball and try this. Hopefully, they will work well for you!
