To make the wicks taller. I was just going to cut out the bottom of the 5” and slide a smaller one in. Weight of the dirt will hold them together

No need to glue the risers,I would look at the stiffness of the tote bottom.Your drilling a lot of holes.So wider and more supports I think is better.An up side down grocery basket cut to the right height would work,lots of holes and strong.
I used same dirt for the wick.Yes cover the gap between so air can get in but not light.Use the lid , works well to keep the surface damp.

Thanks! that soil looks good. Like the trenches too. Do you feel that the trenches are important, even with all the stuff in the soil? What are you mixing in to the trenches?
Yes this has been my best grow ever , water only the whole ride , we thought the soil might be too hot , but once the roots hit the reservoir it was off to the races , yes I like to do both nutes in the soil and the trenches were straight tomato fertilizer high in calcium

So, almost commited to this direction for next grow. My soil is ready and I've got the containers picked.
I'm gonna stack 2 of those rubbermaid containers, and have 2 units side by side in my flower space.
Hoping to have a decent reservoir, so thinking about using 6" PVC for the base.

With this in mind-Hope none of these questions are too dumb.

-Anybody have a line on any net pots 6" deep? I'm assuming i want the pot to get to the bottom of the reservoir. This is the deepest i'm seeing-https://www.amazon.com/Tectsia-inch-Heavy-Round-Design/dp/B085YD8TJ8/ref=sr_1_2?dchild=1&keywords=6+inch+net+pots&qid=1616466715&sr=8-2
-how do you deal with the gap between the two tubs? i know we don't want light getting into the reservoir if possible.
-can I pack the net pot with soil, or should i fill it with something else?
-if you use cut PVC for the base, are you gluing them in or just letting them free-stand?
-anybody using an overflow hose to preserve the airgap? I am thinking to have the top of the 1/2 hose at the 6" mark, consequently keeping a 1/2 air gap, with the hose from both tubs going to a 5 gallon bucket for overflow.
-any issues with funkiness in reservoir? Any reason to put anything in it.

Lastly, I know some of you have had success with living soil and SIPs. I would love to hear any thoughts you have. It seems like a great idea, and i want to make sure i am doing due diligence before I drag 60 gallons into a relatively immovable space.

As always, thanks for the generosity of sharing your thoughts and experience.

Much love

sorry I've just done what i've done with what I could find and don't know if it could be better. on one i have with pvc support I drilled small holes in the PVC so water gets inside and the basin can hold more water. but i hope doing that doesnt make some chemicals leach out of the pvc? I haven't been able to find info on that being a problem. but pvc won't move with weight of the dirt on it. hose overflow would be nice instead of just a hole. I just do water but i like the sound of the stuff these guys are puting in, Labs or whatever it was, if you're into that. Someone suggested 20% perlite and 80% pete in the wick so I went with that. You can stuff some rolled up old landscape fabric in the gap to block the light gap. I still need to try making a cap. I mulched instead. You may have to top water to get the wicking action started.

I’ve been adding straight tap water into mine.it has about 3 ppm of chlorine in it. Hoping that keeps it free of the nasties.

I'm getting ready to transplant into my Earthbox Jrs as soon as I get my dna results back! Within the next few days I should be up and running.

I'm noticing how warm the top soil is lately.Is this normal?The temp on my cement floor is around 65f but the inner tote is quite warm to the touch.Could this be the dry fertilizer ive been top dressing with?Its like one big compost pile under the lid.LOL.

surprised me to see such a lack of roots at the bottom of this 5g sip planter. It's like there's a inch plus layer right above the wick plate without any roots, and none at all peeking though the plate into the reservoir. The plant wasn't that big, but why not make it to the plate?

is that black part the wick? is it the whole diameter of the pot? Just trying to understand. was it homemade?

Its hard to see in this pic, but the plate is about two inches shorter and sits on the rim of the rez, and the over hang is where the overflow aeration holes are, and the platform has two curved cups that get filled with soil to act as the wick
they are called eco grow pots

this is the same type plate only from a 7g pot. I'm using it as a swick riser eliminating the tub of perlite.

it's working fine as you can see. Bubba Kush chopped her today, loads of seeds either from the 4 nanners I found, or from when I brush pollinated a Widow cola I flicked the brush over a cola of the BK. Not a seed seen on the Widow...yet

Ok, almost finished the planter using 31 gallon totes.... And have almost made it through the thread--Whew, that's a lot of posts!Will post a couple of pics tomorrow. I have a couple of questions.
-For those of you using living/no till soil, anything special you need to do/or do regularly?
-should I use a cover crop(clover) or use a cover/plastic over the top?
-I notice that some people put the lids(with the middle cut out) over the top. Wouldn't this stop air from getting down into the reservoir? I have the overflow connected to a tube going to a bucket, do there aren't currently any air holes on the sides.
-I know @Tim Fox doesn't like to use cloth at the bottom of the grow medium. I'm leaning that way. Any strong opinions for?
-I have very low mineral well water(around 75PPM) and about 40 of that is Calcium. I see that a lot of folks were using Calmag in some form or another, especially if using RO water. mine is pretty close to that. should I be using Calmag?

I've got 4 clones that will be going in the 2 30 gallons. They are currently in 3G fabric pots. I'll transplant as soon as I feel solid on my soil.

whoa, nice photo. that's very weird about the seeds. Well you grew it great, but maybe the drainage aeration hole is too high on that. It shrinks the air gap. But I can see you can't go too low with it either or it won't hold any water. maybe that's the roots issue reason
