Coco growing in a Wilma system

Hey guys,

Just a quick one. Recently converted from soil to coco/perlite growing and i'm absolutely blown away by the new growth rates! Safe to say i'll be sticking with coco for the foreseeable future, but the regular hand watering which I'm now doing every other day is becoming verrrrry boring and time consuming.

I was looking at transplanting into a Wilma 4 x 11l pot dripper system, but I'm unsure whether allowing the runoff from my coco to re-enter the the reservoir will interfere with the overall Ph or not? no idea.

Ideally i'd rig it up as drain to waste with the runoff being collected somewhere else, as I know this would keep my reservoir Ph stable until its time to re-fill it, but don't know if this is feasible with the Wilma system.

See link here for description:

Any and all advice will be much appreciated!

Cheers & happy growing!

How bout a table and pump on a timer i do see run off going back into resiovors on that vaderogs youtube channel is a example he runs coco floods it it drains back in without airstones either it creates its own DO with the waterfall effect. So id say monitor ph for awhile maybe after awhile itl stick i used test run off of coco plants all time i would even test coco run off of brandnew bricks from botanicare think it was like 400ish ppms and figured that was clean so never worried about it. There will be fluctuations as plants use nutes or h20 up it changes whats left but surd u can do it

Thanks for the replies guys, will take it all on board! I reckon i'm gonna go for it and get the Wilma, will save me a ton of time from watering. D'you reckon I could get away with using 6.5l pots? Is 11l overkill?
