these are my very first manifolds I started with.

If somebody wants them and will just pay the shipping I will give them away, or even trade for some seeds maybe?

minus the little red sprayer jets, they are too precious to let get away

there are just 3 in the pics but I have one more still attached to a pump

Ill swap for some seeds G13 X WW, If interested how many seeds is fair for you?

Awesome. I'm not too sure really. pm me an addy where I need to send them and I'll go tomorrow and box em up and send em out and see what it costs and we'll take it from there, sound ok? I think a flat rate box might be cheapest but I'll check

 

[PetFlora]

PM on it's way

I thought I would be able to make aerobuckets and maybe sell a few but I did a writeup for a guy with a parts and price list and found out they cost a bit more than I thought and I would probably have to charge $60 per complete bucket to see any profit at all and nobody wants to pay that. Even the manifolds alone are too bulky to sell online because of shipping. Hard to determine actual cost of manufacturing one w/o knowing how much per foot PVC is and how do you know how much glue used per??

Low Pressure does not require adhesive. I never had a junction pop off under low 'pressure'

selling unassembled could help your business model considerably

 

[completenoobie]

I was trying to sell only locally but I have given up entirely. I am neither a good salesman nor a good manufacturer. I did make and use a few without glue but I did have problems so I glued everything. I was trying to leave them unglued just in case the insides ever got funky I could take them apart and clean them but I didn't have good luck with that. Some I couldn't get apart as if I had glued them and others wouldn't stay together. Tolerances in the manufacturing process not to mention different manufacturers, so I just went back to gluing them all.

that does make sense though, sell them unassembled. I just got too many other things going on now though to warrant dealing with the headache.

I am back in school after a disabling on the job injury. That is more than I can handle at the moment.

told somebody privately I would post a pic of this ridiculous contraption. It is my sampler manifold. Casa de Pot quit selling my favorite micro sprayer heads so I bought a sample bag of most they had in stock, 360 or 180 mainly, just to see if any of them would suffice. put a bunch on one manifold to test them, have since changed most out to the little red one I like best so I can actually rotate this one through active duty

Assuming those heads spray 360*s, in a bucket like that you only need 3, each at 1/3 the circumference. Most people way over spray

What are the issues with over spraying? Mind you that one is a tad extreme lol. I always had one or two clog so the extra sprayers were nice to have.

Roots only need X amount of nutrient. When roots get saturated they swell (look like swollen spaghetti) this significantly slows nutrient uptake and can lead to root and stem rot

 

[completenoobie]

is it the actual nutes doing the damage or just the water, like waterlogged?

I have changed over to infinite control of my pumps. I never thought about the pumps running for 15 minutes causing a heat buildup but it probably does. Add that to overspraying and I've got problems.

However, that particular bucket hasn't been used in quite a while. Perhaps I should change out the manifold before doing so.

I am now running an arduino to control relays that turn my pumps on and off. I tentatively set them at 5 min every half hour.

Is there a better/more recommended schedule? I have the ability to turn them on/off for a millisecond and then back off/on for an inordinately long time, like months or years maybe, not sure what the code can handle. Point is, I have nearly infinite control of the on/off cycle. So if there is an absolutely optimum schedule that anyone knows for a fact is way better, let me know and I will reprogram the boards.

So what about a flooded root system like DWC? Why does that not lead to rot every time? No pet I don't think it really matters with low pressure systems and I don't think it's the amount of water sprayed but I could be wrong, no expert, just enough fails to know what not to do lol. I have sprayed 24/7 just to keep temps in the chamber down with chilled water but as for the amount of spray heads I truly don't think it matters as I ran 16 but again a few would clog each time.

With low pressure I don't think it really is critical to dial in times like high pressure. I've ran lots of different times and didn't see any noticeable difference. I was 15 on, 45 off for the most part.

That was what I was running 15/45 but I'm trying to keep heat down not running the pumps as long. I am inside a a/c'd tent inside an a/c'd room but have no other way to keep res cool. Ice packs would be a major PITA

I started to run a chiller, my temps got way high, that's was the only way to keep it cool in the root zone, I actually ran it continuos till it got a bit cooler. I think as long as it stays moist in there and doesn't dry out you'd be fine. I was going to buy a timer board and run short cycles but ditched the sprayers and went back to a flood and drain type setup.

 

[Budley Doright]

I also insulated (silver bubble wrap) the tops of my trays and that helped a lot but a bigger surface than pails. There is a thread here somewhere that shows the shit I went through with rot using sprayers due to high temps. Once I got the chiller going plants were way happier.

These are 15 on 15 off with 16 nozzles 2 weeks in

Very nice, BUT, note the hammocking (roots intertwining with other plats roots). Should you need to remove a plant it's impossible to separate, which is why I only used for veg/clone,then transfer to individual totes for each plant

At least now I don't have to buy another deep cycle timer

removing them has never been an issue as I don't lol. But yup some issues with it pand this is the last run with that set up. The pic was not to bestow the virtues of my set up, it was to show the roots . I am switching to individual square pails but not sure how I'm doing them. It's more for movement of whole plant from room to room for perpetual. When cloning I have roots in 7 days using root riot cubes and perilite so I won't be switching that .
