    I think it was one you you that posted this video once upon a time. Have you guys ever seen other people trying this?

    Think you would have to treat or clean the batting before using it on the plants?

    Also maybe it could be used as a cover layer on top to prevent moisture loss and mold/bugs?

    I have clones rooting and IL be doing a 3 way experiment with run to waste coco in 2 gal plastic square pots, and 2 gal fabric pots and then the polyfill root layer. All with plastic over the trays.

    What do you think? And do you have any suggestions to do this experiment better?

    17min: One of the better NFT vidz out their

    I have the same cool ..junky Ph and TDS tools ..lol

    Honesty I'm a organics type of guy and a very tight one at that

    pouring expensive bottles of sewage down the drain I find disturbing on a few counts $$$ ..lol

    I also suspect that he may trash the plastic sheeting each or every second grow to keep things mold proof

    IMO ...look to Hempy pot method of growing

    that way you keep your drain to waste saves you bucks

    with weed prices about to tip

    this drain to waste will be a very rare thing in months to come

    give it a try

    good luck

    Im actually going to start building mine soon
    Just bought the batting last night actually lol

    I was going to wash mine with a mild bleach and rinse just cause.

    Still kinda figuring out the tweaks im going to make to mine.
    But i have to wait till this run is done so i have room.

    But im basically going to build somethinng similar to the guys vid.

    But im going to make my table a little nicer
    Cause i dont want an unseen hole in thenplastic liner to leak.

    But ill probably use the panda film for the top cover .

    If your asking about using the batting as a top cover? I would stick to the panda because its too breathable. And too much lights for root =algae

    Im going to use the panda on top because i think thats why it works so well keeping the roots in a giant miost air chamber.

    And that guys roots looked great so if he can do it others can too.

    Just my 2

    I bought some batting too from Walmart.

    I'm going to make a real good run at this and see if I want to stick to it. I've been reading into no till organic indoor lately lol must stick to one fucking thing.... It's terrible.

    I have panda film IL be using to cover my tables. Are you going to try to cover the top of the pot or just halfway up the pots to cover the batting roots?

    Are you worried about mold , what's your plan? Any Bennies ? Or sterile?

    With a drain to waste valve? What do you mean?

    projectinfo Well-Known Member

    Man I just noticed a big change in the color and the droop in my clones.

    The ph was high again so I fixed that, then I took out the air stone . Just spray 24/7.

    And in 3 hours they look totally green and standing up...

    Have you ever heard of carbonic acid , the co2 in the water is acidic and when it evaporates it leaves the water with a higher ph. I don't know if it's the cause. Or just luck. But I've literally seen the life come back into these clones.

    Look at those roots!! Success!

    Do you have high levels of co2?
    Ive heard that bubbling can raise ph but i dont remember why sorry on that one

    Cold$moke Well-Known Member

    Any ways to the design.

    Im just going to put a valve in so if i chose i can recirculate or drain to waste i have my reasons .

    As far as the cover goes

    Im using 4 inch blocks

    So i want my cover to be about 1/2 in to 1 inch over the height of my block...

    In my head this should giventhe rockwool more breathing room then just placing the plastic directly on top....
    Dont know if its right cause this is the first build for me too :)
    Then again i thought about leaving the tops of the block in air as well so still up in the air lol.

    As far as mold and mildew. He is running hygrowzyme i think.

    As for me im going to be using this system with a straight salt based nutrient with no bio stimulants at first.
    So instead of enzymes i was just going to try to run sterile with bleach lol
    But i might try the enzymes

    Im sure ill make other tweaks as the build goes on . As i have other ideas to try as well

    Basically in my head its just a BIG NFT system

    And i never had problems with yuck in my nft before . Who knows only time will tell lol

    Im going to make a thread on it once i start building too will be good 2 have 2 of us doing it

    Haven't checked. But I'm not adding any if that's what your asking.

    What I think is happening is I'm pumping co2 air into the water, it evaporates and gets stuck in the cloner and raises levels too high maybe I should leave one plug out.

    Il test ph tomorrow and we'll see.

    Il be working with coco and the full canna coco nutes line, found some great reviews on half dose the whole way through. And IL be timing and regulating the water flow for minimum run off. Shouldn't be too much more water vs a recirc.

    I'm only vegging enough to get established then flower, lolly pop, quick turn over monster nugs I'm hoping.

    Man if you lived closer i got almost new bottle of coco a and b lol

    Ill be vegging for monsters lol they are going to veg while my other run is going then straght into the room

    projectinfo Well-Known Member

    Nice haha it'll be a good all around comparison test.

    What drove you away from coco?

    Cold$moke Well-Known Member

    The mess
    Flushing is a bitch

    Its great yet i hate it too

    projectinfo Well-Known Member

    I heard 20% runoff = no flushing

    What kind of coco did you use that ya got gnats? I'm using cyco coco platinum series. Pre washed, buffered, treated with camg. Supposed to be good right out of the bag.

    Then, next run IL use hygrozyme and re use the medium no till

    Any ideas how to keep flushing to a minimum and gnats at bay for coco?

    Cold$moke Well-Known Member

    I always flushed i know there are many who dont but i did at the end of harvest just my preference

    As to the gnats im unsure if they came from the coco or not i was using canna coco

    But fromm potting mess to carrying bags of soil

    I just did away with it and put it out in the garden

    Dont get me wrong coco is a good medium
    I liked the way it grew things just not enough to keep it.

    I like to just be able to get rid of the old grow by flushing it out on the gardens :)

    Cold$moke Well-Known Member

    Truth be told id like to figure out how to do this without rockwool too but i think its how it is going to have to be
