Each tub cost me around $18 (ish) that was without me trying to save money. That includes the price of all components. I probably could have made something very similar with junk lying around my house. Last year i made em with with home depot buckets.

your setupā¦
Super Simple and the price is super low for what those bad boys are going to be producingā¦
Yes, for the wick to work properly the net cup would have to touch the bottom of the reservoir.
I can tell you that I have built a few SIPās and many of them have net cups or similar in them as they are inexpensive and effective.
However, I have been using Perforated Drain Pipe (PDP) like you have in your buckets.
For the ease of DIY and $ I will be staying with PDP.
Hell yes they doā¦ 
There should be so many dang roots when the system is running properly that you will see roots when you look down the fill tube.
I have had plants in flower power through water like nothing else I have seen.
Another benefit of SIPās are that if the Res runs dry the plant will not suffer. The Sipās are wet enough to go a bit without water. Of course size of the SIP will depend on how long they can run dry forā¦
All I gotās to say is once you go SIP you will not go back.
Only problem is getting enough SIPās set up for the entire grow/grows

You got the idea now ^^ Itās not so about the money but about maxed density. Initially it was to lower maintenance for high density/fast turn-over selections from seeds, iām now using it sometimes as āexpress filling for jarsā. The concept only work if the plant donāt stay long inside, around 2 months top.
Itās too sexy to donāt mix that with the concept iām just discovering lol

i have to agree to a certain degree i would of never had disturbed my perlite bed if it wasnt for the isdues it was involving perlite dust would clog the auquavalve shut ot full flood but having plants growing in sip they grow just perfectly is just a bummer i didnt have time to resolve my issues before being disabled now this setup is not in my current plan as i canot deal with its maintenance
but sip pots could be something i can desl with in the right setup

I have watched the float on the two I have side by side. I had to raise one so the canopies would be equal. When I did, the level of nutrient/water dropped a lot faster.

Hey Dirt, I would check the link farm on my thread for some useful diy tutorials. The RIU SIP thread, https://albopepper.com/, and @Maddawg ās tutorial are some good starting places.

I went to the basement and checked and a 5G Dirt Pot brand, which is 11ā in diameter, fits perfectly into my 5G buckets.
So all I need is a bag of perlite to make the wicking bed, fill the thing up, drill a water hole a few inches below the top of the perlite bed, and plunk the pot in and Iām in action! Going to try this if itās that damn cheap, Iām having fun experimenting a little and everyone says autoflowers like a steady water and nute regimen for best results. The dirt itās in is pretty rich even if it was used once, and it is peat and coco based, so Iāll probably scratch in some fertilizer now into the top few inches before the seedling roots out, and just do a probiotic bottom feed no bites. In the future if this works Iāll probably grab some of these tall 7G pots to stretch out the soil water tables a few more inches, this is the place I get my pots from now, good stuff:

you wont get much root pruning from air gap since perlite will act as an hydroponic medium
its constantly moist as its wicking

Maybe I should put a few flat 2ā thick rocks between the perlite and pot bottom? I want to cut a few 2ā Xs in the bottom of the pot so roots can dangle through more easily, though I know theyāll grow right through
