Wow, that has to be a quote from a while ago! LOL The 14/18 worked really well. It is a bit tall, but that's only an issue if you have vertical limitations. I'm sure I'll use those again. The other ones I mentioned -- the (basically) 5 gallon pot in a 5 gallon bucket, only held about a gallon of water and needed to be filled daily. The plants in them got to be 5+ feet tall, so if you are going that way I would start late so they don't get root-bound.

If you are going to run SIPs outdoors, I recommend either digging a hole and dropping the res part in, or using something like straw or some light colored fabric to keep the res out of the sun. I think keeping the water cool is good for the standing water, and good for the plant. The bottom line for me is that since I'm in a situation where I can put plants directly into the ground, nothing beats mother earth. SIPs are great for outdoor patio gardens, or if you are only doing planter/pot gardening. But if you have access to good soil and open ground, for me that has grown the sturdiest healthiest lowest maintenance plants. YMMV

Last year, I wasn't on RIU much. Read your SIP thread thought I would reply.

Glad you found it useful, a lot of people have contributed a lot of good information to this thread. SIPs definitely have solid advantages, it's just finding the right fit for the situation at hand. I look forward to hearing how your grow goes :)

Is anyone doing a sip no till style. How are you guys re-amending?

My outdoor SIPs are no till. I don't do shit to them over the winter. I leave the root balls in them all winter and don't even bother covering them. In the spring I amend with some lime and a little bit of worm castings. I might scrape out a little bit of the old roots before planting. Then it's just organic slow release dry ferts. This year I'm going to try a top dress with worm castings, Bu's Biodynamic and bokashi. I'll probably add some azomite as well. I use my soil for about three years and then add it to my yard landscaping.

Cool so just a top dress and then a layer of EWC.

do you have earthworms in it? Also do you mulch or use the plastic?

I love the cover crop, @Jp.the.pope -- the only thing I've used (mostly outdoors) is red clover, what else are you using? (sorry if you've 'covered' that already... my memory is weak and my laziness is strong...)

I bought a micro clover mix from build a soil. It has like 12 different kinds of seed. All help fix different nutrients.

I'll see if I can find a link. On a side note, all my plants are loving it. Sip and no sip.
