Im currently doing the rounds with wholesale changes possibly afoot...I needed a new light, so I went LED - all new, and now we doing OK. I then thought 'since were changing the light, why dont we have a go at hydro? - so I bought coco - and havent looked back thus far...in fact im sure im not, but I feel like im smashing it I recently bought a camper van and like to get away which kind of fucks with the grow - short bursts do anyway. Long term lights off doesnt cause too much harm, up to 3 weeks in my experinece, but the lights are off and nothing is doing... i tried a passive hydro system, Blumats - loved the idea... That kinda worked on their day - ish, maybe, kinda/wanna/sorta didnt really in the end..., and was very unrelaible over periods of days, so the natural progression is just to go all out and go hydro, for the summer anyway. I fancy the IWS system as its largely self contained, apparently it adjusts itself not to over flood, and is bulletproof relaible...and if im only away a few days i can also reduce the res capacity so if I did get an issue, then it could manage the overun.. Im petrified of the nuteage situation. I had problems stabilizing my PH with the blumats in my 47L res and now thakfully back to hand watering - but that wont do at all when I need my open spaces - . I never filled it over about 30L anyway, but my plants were massively over fed which means my PH was probably out. Also blumats in coco dont create runoff so I assume some fo that over feding would have been roots related... In short I want to use an Auto PH range that just needs dosing to the water...does this exist? Is it any good? is it massively expensive ?- who has experience? if any? Im happy to aeriate with a pump of course, but if i could PH without PHing in a 100L res that would make my life a whole lot simpler...and easier. being a long term organic grower Ive never really had to bother about dry plants until recently. Ideally I'd like to fuck off for the week, but if I did that my weed would never grow - part of me wild campervanning is about my weed and devices on tour anyways i digress.
