Some of you guys are ridiculous. Y’all have one bad result from a product and never question if the method or user was wrong. I’ve used floraclean to flush, make corrections to my coco if nutes are out of whack and I’ve used it to flush coco after grows to reuse. There is definitely a reduction in the amount of water needed for flush. I’ve gone from 5gal of water for a flush in a 3 gal pot to having to use 3 gals to get lower ppm with the first gallon being 2ml florakleen and the other two galIlons straight water… definitely not sugar water, it contains absolutely no sugar or basic carbs. I’d say it’s more like hydrogen peroxide, when mixed at 2ml/gal I’ll usually see tiny bubbles form on my perlite. It’s worth a try if you’ve trying to save time and water, but water will get the job done.
