SIP thread -- (Sub-Irrigated Planter)

Well that’s a good tip for newbies. I mean from some of the stuff you see around here. You have to tell them not to stick their hand in the fire.
You're absolutely right. Anybody reading this far into the thread, who doesn't already know, roots breath oxygen. Don't seal them in! Lol

So compare your plant to some of the others you see.If I didnt see the sip Id say thats a hydro plant.
For sure. I'm comparing it to the dwc plant I grew and I see a lot of similarities in growth rate. I dunno if I could've filled the scrog without doing hydro or the sip. These pics are from going into week 3 last years hydro. It stretched a shit ton more but didn't have much more mass.

I'm working on setting up another 4x4 and had some ideas for DIY this time instead of buying more earthbox Jr's. they work great, but in my planting style I have to go 2 per sip. the long rectangle footprint also makes them harder to move around. also, the overflow hole means if I need to move them while they are full, I manage to spill and make a mess no matter how careful I am.

Grabbed 9 of these from my local hardware shop.

First question, are these safe to use? they are LDPE which is a softer plastic. seems like it will be fine but wanted your all feed back before I proceed.

My plan is to use these "plant warrior" 5 gal pots on top, with another smaller square 1/2 gallon pot upside down (with holes drilled all over it) zip tied to the bottom to serve as its "foot". This would then sit inside of a hole I cut in the lid of the tote.

instead of a drain hole , I'm going to use a small valve attachment on each one so I can connect a drain line to each tote. this way I can run all the overflow into a bucket and easily carry it away instead of mopping everything up. nice and clean and less humidity spikes after I top off the totes.

add a 1" pvc fill pipe and I think this will be a nice little sip that can be easily moved w built in handles,, has enough soil in the pot for a full water only run, has an easily removeable lid to check root growth and/or clean the res as desired.

change my mind. have the day off work and going to either bang these out, or give up and go buy some city pickers from lowes.

Like this? Would work just fine. Lid on the tote needs to be light sealed though. Not sure how that would work. A925AC7B-049C-479F-AD1D-EB32E38741AA.jpeg

Howdy! I have a 2 week old auto seedling going in a Grobucket using coco, just wondering ,on average, how long it takes for the plant to start drawing water? I've been top watering/feeding so far but I filled the bucket a few days ago and the level hasn't changed at all yet.

Thanks,
Grazz

these are expensive but considering they have the built

exactly! the bottom "foot" sits an inch below my lid in my design tho. I have been trying to figure out the best way to create a "gasket" seal, and figure cutting it a few mm smaller than the pot would give it a nice tight squeeze in fit, and then just running gorilla tape around the seal of the tote lid and pot should do the trick.

you will know :) one day the plant will just have a ton of new growth and then your life will change forever.

Yes. So you have to find a tote that works hight wise with your pot and riser. Would give a big Rez for water. As you said a nice friction fit would be all that’s needed. A little light in is ok. My totes let a little in.

My soil even when wet will wick water. One way to tell is use a moisture meter to see if the bottom part is wet.

If you have a drill press you can make a hole saw to get the perfect size.

I guess my biggest question is if I can use those Rubbermaid totes from my previous post, as they are LDPE plastic (but they don't specifically day food safe/BPA free).

Is there concern of leaching plastic toxins into my res by using these? or do I need to find some better totes that will be safe to use.

on my list of wants/needs. I don't have much of a workshop and only have a little shared outdoor courtyard to work in on weekends. but that would be awesome.
