flushing before harvesting?

i been reading on this forum and noticed alot of people talking about "flushing their plants" before harvesting.. do you use this on an outdoor crop? i'd like a crash course on this because im very interested in making my crop as potent as possible

You can flush to a certain degree, just use clean water, but no need to flush if grown in the soil as not so many chemicals in the soil, personally i dont bother, let nature do its thing

i would flush even if grown in soil or hydro, 7 to 10 days before harvest, i would do a light flushing in soil, get all nutes out of bud smokes better! just my thoughts

so basically all you do is rinse it with alot of water or sumthing? need more details plz

You want to put in 3 times as much water as the pot can handle, this usually is noted by the pot size, a 3 gallon pot which is about 12" in diameter would take 3 gallons to flush a plant with.

You want to PH the water too, dont get careless, use the same ph you use to water the plant with.

Thats it, after youve poured all the water in you let the plant sit and be flushed

When you say outdoor crop, is that in pots or in the soil/ground/earth?,as i have grown in both and do flush in pots, but in the earth, man those roots go deep, i grew a small 9 foot bush and those roots went everywhere far to big to flush, let us know the size and what your growing for better advice
