Can i just use some amended soil for my wick?
My understanding is that you want to keep the water in the res nute-free, so if by "amended" you mean that you've added nutrients to the soil, then I would suggest just using very plain soil in the wick, or as HydoDan said, Coir works also.

If the water gets nutes in it then you need to ph it, and that changes the game. Some people treat the water like hydro and feed through the water, but for me that defeats the purpose since one of the primary benefits of SIPs that I love is that they are inherently simple and low maintenance.

What growth difference are you seeing with sip pots compared to regular hand watered smart pots
Growth is about the same maybe a little faster but not much... I ran three plants in the exact same everything...
One developed a calcium deficiency so I added cal mag to the res... no problems... Didn't experience weak limbs as others described...

Damn wtf i thougjt that was part of the reason to do a SIP is way faster growth? I guess the only benefit is less water usage?

The long and short of your sip design is to have the water feeding upward to the medium to a certain extent. The total volume of your container is most important when choosing flow.

I’ve been trying to figure this out for a while. I suspect that individual grow style plays into it. If your habit is to trim hard than you can keep on top of it, if you tend to let your plants grow on the wild side (as I used to) I found they grow a lot more, both leaves and branches. The first time I grew in a sip I compared it to kudzu.

Sup fellas...
3 inch pvc with an elbow and perforated tubing with holes on each side then added some rock and placed landscaping fabric over top. This is my first time making a SIP..... you guys have some tips for me? I will be making more pots tomorrow and wouls love to hear how i could make one even better. How far does the water wick into my soil? Do i have to water the top once to saturate soil? Thanks guys
