Sub-irrigated planter
From Wikipedia, the free encyclopedia


Sub-Irrigated Planter
Sub-irrigated planter (SIP) is a generic name for a special type of planting box used in container gardening and commercial landscaping. A SIP is any method of watering plants where the water is introduced from the bottom, allowing the water to soak upwards to the plant through capillary action.[1] It is possible to automate the watering and thus SIPs are popular with professional landscapers in buildings or urban settings. SIPs are available as products, under brand names such as Planter Technology[2] (commercial) and EarthBox[3] (consumer), Ollie Plant Sipper[4](consumer), The Refuge Garden (www.urbanrefugegardening.com) (consumer/commercial) or as do-it-yourselfprojects made from plastic buckets and boxes.[5]



Would love to hear about your experiments, projects, failures and successes. :)

I was thinking of purchasing a earthbox myself, a sub irrigated planter. I just don't know how well it would do with organics. I brew a lot of aacts and use shit like fish hydrolysate. I don't think that would go over well sitting at the bottom for more then a day. I guess if you had some really nice soil and used only plain water it would do very well.

I'm doing a couple right now. One is based on a 14 gallon Rubbermaid container inside of an 18 gallon. The other is tall narrow #7 pot mated to a 5 gallon bucket. Both still need to have their drain holes drilled -- btw, how much (in inches) of an air space should I leave between the water line and the bottom of the soil container?

Being that I'm still in the process of building mine, I have no first hand experience yet, but I've been reading as much as I can on them. Hopefully @hyroot will join in, I believe he uses an organic soil mix in his. There are a lot of people experimenting with them, I've read bits here and there on different threads and journals, maybe we can focus the information here.

I know @Tim Fox just ordered an Earthbox, but I think he's going to grow some tomatoes outside with it this summer, and do an indoor grow with it next fall or winter. Tim pointed me to some great online resources, like the instructions in the attached file from http://earthtainer.tomatofest.com/ I based a lot of my bin design on their instructions, but instead of using two 18 gallon and cutting one up, I used one 14 and one 18. I will definitely use their water level indicator design though.

Yea man ,I just ordered a earth box, it's going to fit my grow box really well, I will put some pictures up when it gets here, @Humanrob those diy sips look really good, maybe hyroot can shed some light on your wick choice, of there is enough slots?,
Everything I have read said one inch air gap

Thanks, couldn't remember the gap. My previous design had too much air, this one might have too little, but that's easy to change.

I'll definitely keep an eye on that. I was thinking maybe you could top feed with compost teas, just making sure not to go overboard so it doesn't reach the resivoir at the bottom. Its also perfect size for my area and I think holds nearly 2cft of soil? I might run 2 plants in it.

Yes , the earthbox holds exactly 1 bag of soil product, 2 cubic feet, or around 17 gallons, Chose some type of living soil, I know in the octopots they ad nutes right to the res, I am going run Water only the whole ride in my earthbox,,, my last grow was water only the whole ride in 3 gallon containers with FFOF

more earthbox from buildasoil on vimeo
lol, I laughed in the video when he said at 13:50,, it works like using an airstone ,,so why go thru the cost and trouble of appling anerobics?,, So i chuckled and said,, then why not just use the air pump, save the trouble, save the money, ya

Go 15:45 in (+/-) and you'll also hear him advise to let the res get completely dry between fillings. So apparently these can be used simply as an alternative method of watering, without any hydro-hybrid pretensions. I plan to keep my wicks moist, but that's just me.

Edit: but it is an interesting video, and it is good to know that if for some reason it runs dry, its not the end of the world.
