why is your pump coming from both sides? that will not work i don't think. you need to use end pieces at the end of the hose. just have one pipe leading to each row of slabs and have the end of the pipe blocked with a end piece. with your plan the water will be fighting it's self, i don't think it would work like that. unles i am misunderstanding your diagram that is?

excellent - exactly what i needed - now when im going to use slabs..

do you run to waste? or recirculate?[/QUOTE]


I recirculated and changed out one to two times a week depending on readings.

What kind of drippers are those you use and what kind of flow rate are you getting per drip and per day?

thanks

Thanks FT...MJ does not like to be over watered so I would use caution in running a continuous drip. Also those slabs hold a grip of water. I ran my drippers for 1/2 hour twice a day. I have since moved on to bucket systems and also organic soil.

As far the the flow rate on the drippers...I'll see what I can dig up and let you know.

Ok i gotta ask , whats the difference between pressure compensating drippers and
the regular ones?

[gaiusmarius]

the pressure compensating one, like the name says, equalize the pressure, (flow rate) BUT they normally speaking require a stronger pump to run them. also if you use a one way valve after the filter in your watering system, even the non compensating ones run fairly evenly. they are plenty good enough for my purposes. specially considering how loud those 4 bar bigger pumps are.

I don't know anything about coco and have never used it (just checking out this forum, building up interest in coco), but I do remember seeing the Cocotek AB cubes (as in ABsorb) for flood applications in a GH catalog somewhere. It's made with a more absorptive material in the center.

i am sorry to say that i have never tried the coco cubes that you can get instead of RW cubes. i plan to buy a box as soon as the RW cubes are all used up. i would imagine that they work just as well if not better than RW cubes. it would also mean that there is no medium change from rw cube to coco slab, although with a bit of care you can plant them without any transition stress showing. still the coco is a much friendlier medium to our planet, than nasty old rock wool. that's reason enough to try them out.

haha thanks Alex, i think lol.

i am like a kid at a candy store with all these different coco setup threads to follow. i always knew coco was very forgiving and can be used in many ways, but just how many is only slowly becoming clear lol.

i am loving the enthusiasm everyone is showing here, it's really cool to experience.
