Trying to work up a parts list and quote for automating 8k of coco on 4x8 trays

[oceangrownkush]

I am looking at different timers/pumps/drip line equipt, ect and trying to figure out how best to go about this.. The Sentinel Drt-1 timer seems like it can get the job done, and with 2 outlets I could run 2 reservoirs off of it.

I am wanting to do 1 50 gallon res per 4x8 table. There is enough floor space to have the 50 g right there next to the tables so why not?

The thing that is getting me is I don't know how to run the drip line, and I'm not sure how powerful a pump I will need to feed a 4x8 table without some of the lines getting less pressure than others. I am wanting to do coco dtw w/ multiple feeds daily in flower 2-3 depending on what ends up working the best.

Any input or direction to threads where the plumbing in a grow like this is pictured would be greatly appreciated..

no comment on the hardware referenced above. im admitidly biased towards diy solutions, which i think you are not interested in.

regarding your pump question.
what flows are you expecting? between 1 and 5 gpm, i reccomend a diaphragm pump. Its a simple PD type pump that will deliver between 40 and 80 psi depending on make and model.

no clue what emitters you are planning on using, but i would suggest running the smallest flow rate emitters possible, and simply running the cycles longer. this will allow you to maximize the amount of total emitters you can have on any one single zone without maxing out the pump duty cycle.

i run a small ish system myself with a shurflow modulated "smart sensor" pump. it basically ramps a pwm signal up or down untill a pre set pressure is reached at what ever flow rate is being demanded of the pump. it will max out at like 7gpm i believe.
its roughly equal to what my garden house produces wide open.

a cheaper solution, would just be a demand type diaphragm pump. you will require an accumulator however, so as to prevent rapid cycling of the pump. A pressure regulator and some gauges etc will be required as well to trouble shoot issues here and there.

I was recommended Wayne 1hp pumps from a member here and they are strong enough to water two 4x8 beds at a time. They are 125$ shipped on Amazon. I piped them to PVC manifolds with four octabubblers per table.with fan jet micro sprinklers at the end of the drip lines. Bitchin set up.

Used 44 gal brute trash cans for res' they needed to be filled every three to five days

I'm gonna come back and edit this post when all is said and done, I'm just now getting an idea of how this will look in the end.. The homeboy str8edge helped with directing me to a few threads, here on IC and elsewhere.. Basically I'm going to be following Jackmayoffers approach with the octabubblers and 1hp pump.. If those pumps oti$ recommended are solid I'll probably have the 50g res around every 2 tables.. We already have a shit ton of 50g reservoirs as it is so might as well use them..

would you like to share some of those links? no need to keep em to yerself.

There's also a thread in the coco section here by sureshot66 that is very informative/inspirational

wow ok just google jackmayoffer drain to waist *yes -waist*

Interesting.. I didn't know people were using pumps this large to top feed.


I'm in the process of building out a proper 8k setup with a friend. We will be doing top fed coco on 8 - 4x4 tables.

I actually have a barely used 1hp Hayward Super Pump (self priming) just laying around from a old house I stayed at with a pool. Sounds like I might have to plumb up an epic dripper setup.

I've been previously just using 1/6 HP sump pumps from harbor freight to feed a couple trays at a time w/ 1/2" and 1/4" flexible tubing.

One HP pump for a 4x8? I use a 600gph pump and that is watering through a drip top feed system. Plenty of flow there. I am using drip stakes. This is interesting, good thread, I'm going to check out that link.

Good luck with the build OGK!

1hp for multiple 4x8s. Another member, the one who guided me on my bed build, is bldswtrs. I'm not sure what the thread title was, but if you look up the username, he gas a thread with parts list and the places to get them cheap.

Ok I get it now, I was going to say, that seems like it would shoot my drip stakes across the room lol.

from an engineering standpoint, a sump pump is not a good solution for drip emitters.
if you can get it to work on the other hand, more power to you.
a smallish diaphragm pump imo is the better solution, however the price would be the same, or possibly higher.
