SIP thread -- (Sub-Irrigated Planter)

[myke]

I wanna try planting a seed in one.

Last round I had a small plant that never really took off like the rest. At harvest when I tipped the soil out it had a bad smell.Too wet. So it’s possible to overwater. I’d think a seed would need top watering for a month first. Idk.

I feel with a cover crop growing simultaneously it might just make it.

I've grown quite a few plants from seedlings in the sips. I popped my seeds in Jiffy Pucks, then transplanted directly into the sip, and gave them maybe 1/4 cup of water. Seems like it takes 3-4 days for the roots to hit the reservoir, and they're off to the races

How big are those sips?They look good.

 

[GrassBurner]

I want to say they hold 1.5 cu ft of soil. Footprint is 20"x24".

Dynastygenetics Huckleberry dieselv2 went into a 27 gallon HD tote SIP this evening. I use drain tile wrapped in landscape fabric and a central wick of vertical drain tile with soil. I use Docbuds soil that has been cooked for a month.

Decided to try out some aeration channels. Just 4” perforated drain tile with tile wrap.

here is my bulkhead and water level indicator. The bulkhead is about halfway up the drain tile. I think it holds about 4-5 gallons of water. I can also turn the indicator downward to empty the SIP if needed. Need to change the tube it’s pretty dirty. Maybe just needs a tooth brushing. It’s a rubber grommet with a plastic 90 and some clear tubing. I will raise the SIP up so I can actually drain it. Docs method changes drenches so I will drain one out if it’s not empty and replace it with another.

Here is the girl. She’s about 36 days from seed.

Have you tried this SIP yet? How's it working for you?

 

[raggyb]

Lol thx. I’m staying under 4 so I figure one SIP in a 4x4 will do it for yield. This is my first time growing the strain so will trellis her but not scrog yet.

sorry ignore my last i needed to read on. I was wondering if the roots can get through the wrap. i get that you wouldn't want dirt to get through. i was thinking maybe a layer of vermiculite to stop dirt instead of the wrap but wonder what others think?

Most of what ive seen on outdoor raised beds dont put fabric just gravel i think?Will see what shig says.

Yea that's what I figured. It just looked funny to me at first.

Roots do get down there I can tell because the planter hooks up and the growth gets big fast. I wanted to try and minimize the amount of root growth down there a little just to keep most of the roots feeding from the soil. But in the end they get down there anyway.

cleaned up the garden today and took apart the SIPs. Both sips grew to 66" tall and the branches were so heavy they were falling over with fruit.

This one had two 1/2" wicks. It had a few toms with blossom rot but nothing wide spread. And there were two root masses
about two feet long in the bucket coming off the wicks


this was more traditional SIP with a small cup.




this one was a simple colander in a bucket with a hole about 3 " up. The toms did ok but they were from seeds from my grandfathers home town in Italy different that the others.

So which one won the side by side?Or which was your fav since height was the same?

I would have to give the edge to the SIP with the cup since there were no blossom end rots on it.
Both had to have the reservoirs refilled daily so if I do outdoor SIPs again I'll definitely have to use larger reservoir or auto fill of some kind.

I've been thinking of a big sip for outdoors. You could use a big plastic tote with a metal frame. Cut about 18" off the top. Then build a square floating platform a couple inches smaller than the opening. Attach wicks to your pots or fabric bed through the platform. Set your 1 inch air gap, and it stays the same as the water level changes. Would probably have a 100-150 gallon reservoir, with a built in and threaded drain

I remember I saw someone who grew outdoors in a great big tub. Filled the bottom with diapers and then added the soil. I would definitely call it a SIP.
