Flushing with sugar

    Hi, i was looking into flushing products like clearex and flora clean, and it seems that they are made up of glucose and sucrose, and those are useful in promoting bacterial growth for soil and also have some chemical properties that break down salt buildup and help flushing the medium. Although plants are not know to uptake them directly, some people recommend using them for the flush and claim they aid in flushing and replace harsh chemicals with sweetness. I would like to discuss the use of sugars particularly in flushing hydroponic grows, any experience or knowledge about that would be good, thanks

    Flushing as in putting 3 times the amount of clean water through a pot compared to the pots volume is worthless and only kills baby rhinos in Africa .........I'm sure you've heard of growers using molasses in there grows especially towards the end ....the reason for this is not to make bud taste any different or make it magically become more frosty overnight .....I use molasses for the sole purpose of feeding the microbes in my soil ...and as far as flushing I just taper off the food toward the end and water with nothing but water with some runoff the last few times before chop .....hope this helps good luck

    I never flush either. Just feed RO water the last couple weeks in my soilless grows and taper off my ppm in DWC the last 3 weeks.

    It's the drying and curing that makes or breaks the taste and smoke-ability of your crop.

    How do you flush a plant grown in the earth outside? Those flushing agents are just a money grabbing scam in my mind.

    I also use molasses in my soilless/soil grows to feed the microherd and it seems to help. Only organic unsulfured blackstrap molasses tho.

    First off, I don't think there's a purpose to flushing... however....

    The purpose of the sugar in clearex is to maintain an isotonic osmotic gradient . There is a blog on scienceinhydroponics about this exact subject. (the guy who made hydrobuddy).

    Here it is.


    This is nice to know, but not very useful for growing weed.

    When I was growing outdoors we used to just before harvest we would let the plants dry out to almost wilting an water each plant with 5 gal water an 1 cup raw sugar mix. cut around about a foot out from stem. once they are standing proud again. Pull em out shake off all the dirt an wash root ball in sugar water an wrap roots in wet fabric hang in the dark airy place to dry an cure always got a smooth smoke,,,, on any strain this works :leaf::peace::leaf:happy gardening

    If your running organics there is no need to flush, There is nothing to flush, However when I run anything composed of salts, I run those nutrients all the way to the end of the plants life cycle, Then cut the branch's off and put them in a bucket of RO water as if you were to put roses in a vase, same thing. It flush's them faster and In my opinion, more thoroughly, When your ash's burn a nice gray color they have been flushed properly.

    in soil, there is nothing to flush, In hydro, it may be needed to "rinse' the roots of built up salts. but i would do that about half way thru, not at the end. and i'm not going to get into the whole mol-asses debate, leave the kitchen ingredients in the kitchen.

    Great info, thanks for sharing! Might well give this a trial. I've appreciated samples of Clearex and Drip Clean previously but not enough to buy the stuff.

    Flushing takes water. Those pruducts are just sugar water.

    they add sugar to stop the solution from being isotonic.....which kind of seems self defeating. in an isotonic solution, there is less dissolved solids than in your plants roots, and the solids will actually migrate out into the medium to balance the solution. thats all the sugar is for, to stop leaching from the roots....which is what the product is for......which doesn't do anything to the buds....
