The idea of flushing the soil is to remove as many nutrients as possible. This forces the plant to use-up it's stored reserves. Otherwise the plant will continue uptaking and storing nutrients, which will adversely affect flavor and aroma. You'll never release (flush) all of the nutrients from the soil, but a good flush (1 or 2 gallons of properly ph'd water per gallon of pot size) has always done me fine.

If you're in "organic" (natural?) soil...every time you water you're releasing SOME nutrients from the organics themselves. In this case, I stop any additional nutrients about 2 weeks before harvest, and flush the week before harvest.

Trichomes are the ittsy-bitsy tubes with a glob of "resin" on 'em that grow from the leaf surface. It contains the THC among other stuff. If you have good eyes, you can use a 5X magnifying glass to see which stage the trichomes are at, but the pocket microscope is pretty cool to have around.

The white hairs growing out of the calyx's are pollen catching tubes that catch and transport pollen down into the calyx to form the embryo in the seed. They die-off on their own, but will also die if crushed, folded, spindled or mutilated. (or of it's calyx is pollinated)
Rusty Trichome Reviewed by Rusty Trichome on . question about "flushing" and harvesting heyo all i got 2 questions as a total new grower, i got 2 plants of white widow, i think im doing well so far i read alot about "flushing" your plants 1 week before harvesting to flush the nutes off the soil for the buds to taste better but i also read alot of ppl that say its plain bullshit, and it causes the plant to stress what do you guys think i should do asa first time grower? also, i still dont understand how or when i know when the plant is ready to harvest i know that 70% of Rating: 5
