just a thought......try using DripClean...Its an entirely different product than Clearex or any of the other similar products.
i looked it up, your really diggin the H&G huh? lol, but yeah that stuff looks great, i like the fact that you run it during the whole cycle, not just in between changes. one of the reasons i haven't been flushing is because it is such a pain in the ass to do in my system right now. I think i found a way to make it easier though. after this run i will make some upgrades to my res system and try to make it easier on myself. I'll def get a bottle of that stuff next time i get paid. it's def worth a shot.
I find rockwool very difficult to grow in - I think it contributed to the root rot problems in my current system.
To bad you can't run the wheel without a grow medium. I don't know enough about it to offer suggestions... I'm trying to figure out how the larger cubes might be playing a role... larger size taking longer to dry out might encourage rot. Sounds like you've already made the right move with cutting down the water cycle to once a day.
i agree. i think my roots in RW are not great either, as compared to my ventures in dirt, soiless mix, and DWC. i have had success in all of those other mediums. i knew once a day was enough, but i didn't know if twice was going to be too much. it was, you know it can change according to environment and how big and how thirsty they get. i will stick to once a day from now on.
i have spent a considerable amount of time considering how to grow with different or no medium. it is something i might perhaps give a go in the future sometime.
Thats definetly a salt build up. Thats what i would attribute the ph fluxuation to. Salts will kill a plant as we all know. I always use rockwool and find and am loving it. Have you looked into the STG cubes? or perhaps a cover for your cubes. Algea and Salts sounds like a good hypothesis to me. As far as getting rid of it. It would take a good flush and breakdown of the whole system. So to work with whats going on I would try to clean the hell out of what you can and as far as the sat build up goes, and attempt to remove what you can on those cubes. Get them covered so any algea that is around will die. This is what I would do, then take notes of the cause and effect as well as the solution you came up with to fix it and if it worked. This is just my opinion on the matter. Pit said it best try DRIPCLEAN. Dripclean is well one the best products for cleansing, thats IMHO.
I'm glad you concur that its salt buildup, thats way better than mold or something. . . no algae on the cubes yet, covered the tops to prevent direct light. i gave it my best cleaning the last 3 days, and might try to do one between res changes from now on, the pob being if i only want to water once a day if i flush, thats it for the day. i dont like doing two res changes every week with this system. infact i'm unwilling. i think i have a work around though. but the dripclean might make that irrelevant.
maxx actually suggested against the STG cubes, and someone else too i cant remember who, stating that they dont have wicking properties. also i felt them in my hydro store and the were really light and airy. not sure if they'd drip down the top either. I should get a pack, they're cheap enough and at least see if i can do something. it'd be worth a shot considering how much trouble the RW has been giving me. plus i can flood to any level i want so up wicking might not be necessary anyways.
wheel i think your rite regarding the twice aday feeding. A FEW of the vets that chime in, they say there peace, but they never say feed more then once. they dont keep journals but they cant help but pop in. cheers to your poppin season. We luv ur journal, best thing since Christmas.
I'm assuming you are talking about RW vets? not wheel vets? so, yeah thats good to know, i ordered a book on RW before, but they left it out of my order and i never got it. bastards. maybe i should just go buy one at the store. thanks for chiming in, i'm glad you enjoy my journal. i'm trying not to get too frustrated like a good little scientist and just work though it. but of course i wouldn't be offended if i had to work around it some way if i could either. lol.
Looking good despite your issues.
thanks bro. thats why i ran the scrog this time too, and I'm glad i did.
honestly if i get 8-10 oz from the scrog i'd be happy, after having to cull so many plants already from the wheel i have downgraded my expectations. i pulled about 20% of the plants so far from my neglect/who knows what else, and a few of them were big with significant veg time. i'd honestly be happy with 5-6 oz. definitely not a power run, but thank god for the insurance scrog. plus organic. mmmmmm. organic.
