I have done many plants in autopots which are not to my liking except I do love the automation and the self regulated wicking feeding. It is the easiest system I know of. Not only do you do minimal hand watering with the system, your plants will drink as much as they need so you don't have to think about how much to water and when to water.

I'm always looking to improve things so I'm going to try a new automated irrigation system what will use small 1g pots and the medium is always coco. The last grow was done with the small 1g pots and I like that, but it was manual watering and that was a big pain in the ass esp with how frequent I had to water in flower. This system will differ from autopots in a few ways. The most notable way it differs in my mind is I have to control how much to feed and when to feed with this automated system, whereas with autopots you don't have to even think about it. But I like being able to control feeding so to me its not a big deal. I'll use the timer to control how much to feed and when.

My new system is based on drip stake irrigation. and it will be for 8 pots. And its going to be automated so it can be left unattended for days at a time. I am using a 36g rubbermaid Brute garbage bin for a res. A KEDSUM 500 GPH submersible pump. The pump will turn on N times per day and run for N seconds using a NearPow electronic timer. An 8 port Orbit irrigation manifold connected to the pump using a long pipe nipple. Then we will have 8 runs of 1/4 inch tubing out of the manifold all cut to the same length (to keep the pressure on all lines the same). The lines will go in to the tent and along two walls. each wall will have 4 pots. Each pot will have a drip stake in it.

This is the rubbermaid bin reservoir with the pump suctioned to the bottom with an 1/2 inch pvc pipe nipple on the output of the pump going to the top of the res. That will push water up the pipe to the Orbit manifold at the top of the nipple. I'll post some more pics as I build this. Next will be the irrigation lines. I'll post a picture of the lines in a day or so.

I have something similar, but without manifold, only with pipes. DTW is way better setup than autopots. Plants are healthy till the end.
 
Cost comparison of a DIY system vs a turnkey system like Autopots.

I'd need two of the kits with 4 autpots and res etc. Each kit is Cdn $220 so that would be $440 for Autopots.

The parts for this DIY system cost less than Autopot equivalent. About 1/3 the cost of Autopots.

man, what a bunch of lurkers. Not much happening on AFN again. Not much point in posting if peeps are a sleep at the wheel.

Got a spool of tubing today and cut 8 lines of 23' each. The manifold is an octopus of tentacles. I hope the pressure will be in a good place too. I have 8 1g pots ready to go. And a big container of hydrated precharged coco waiting. And the stakes. My plan is load up the coco in a couple of days and do a transplant from solo cups to the pots. Then put a stake in each pot. Fire up the pump. Hope PSI is ok and nothing blows. And watch the stake emitters do their thing and once I see run off I'll turn off the pump. Record the elapsed time. And go from there.

Haha, you’ve noticed that too eh?

Keep it coming though, I’m interested to see the setup and how it all comes together. I haven’t had much problem with hand watering but my current plant is a bit of an attention whore, requiring daily waterings. That and I do go away every so often which an automated system would be great for.
 
i am thinking to automate my feeding for my ladies. and was thinking what to get, Autopots or flora flex or maybe blumats, or make DIY DTW system like your. only problem is i want to feed organically. so what you think guys does DIY DTW system will be ok for organics?
 
I do something similar. Same manifold, but I use a DC pump that puts out up to 80psi. Plugged into a Zooz zwave power strip, automated via home assistant and node-red. I can configure any irrigation combination I want. Right now it's: Run the mixer (pump inside tank) for 30 seconds, irrigate for 30 seconds, pause for 30 seconds, irrigate for 30 seconds, turn mixer off. As they get older I'll decrease the interval -- right now it's 24h.

For drainage I have a low profile flood table that drains into a bin. I did not want to empty individual containers.
For drippers... It's been a journey even though I'm only on my 2nd grow. Used dual sprayers last time, messed with a bunch of different things -- ended up printing hydro halo like things on my 3d printer this time -- working well although I may make them slightly larger diameter or drill a couple side holes.

I was(am) considering just throwing a pond liner in the bottom and maybe, maybe cutting a out a drain hole in the tent. That's a big step, so maybe in a grow or two or three. The other option might be to flip the tent upside down so I have drainage at the bottom. That should get me back the headroom I lose by running an elevated flood table.

Still confounded by nutrients though. Started with canna, flipped to megacrop -- still dialing it in. I don't see how others run those crazy high amounts though. I'm running 3.5g/g and getting some tip burn.

That’s how my drainage is. My floor is lined with a heavy duty canvas tarp ( the type you see on a dump truck,covering his load )..
I have a hole drilled,and the floor is angled up,and sideways,,,just a little,to allow all overflow to be directed to that hole. Works perfect,

I'm leaning that way, but have to get over cutting a hole in the tent. My tent is elevated off the cold basement floor on a couple plastic pallets, so I can easily add some pitch.
