Is Flushing Really Necessary

Question
I Can't Pull my plant out again to change the res, i am about 2 - 3 weeks out from being done. i bought some final flush but i cant use it properly if i can't change the res out. is it necessary to flush the plant??

post a pic of your setup and i can help u i had the same problem use a water pump sitt it in res and let it pump the nute out if that dont work

try just feeding plant organic them add water to it in hope that the plant drink enuff water to flush nute out it self


u have to flush or your weed will taste like chemical

wat nute are u using


if this is helpful give me rep if not pm me and i will be happy to help u more

ok i check out you grow
1st thing first great grow
2 try using only half strenght organic in this last week
3 only add water

jus pour it in threw the top


how much are your plant drinking i sat next time they drink most of water and nute jus add water and finnaly flush u dont have to clean the res out jus make sure u have at least 80 % of water and u will fine

so i am using gh flora series nutes, cal mag plus, bud candy and maxibloom, just switched out res yesterday and only added bud candy, flora bloom and flora micro to 4 gallons of water, almost lost her she is very top heavy because she has been resting against the walls. here are those pixin the last you can see the leaves that have been drying out

daily i am adding about a gallon of tap that has set out for 24 hours

you ever smoke herb and it snaps or crackles? i believe that is the result of not flushing

Hey Mon,

Get a 2nd five gallon bucket. Put it next to the one you are growing in and transfer the plant into the spare bucket. You might need someone to steady or hold the top as you raise the rootball above the bucket lip to transfer it. Replace your water and nutrients or flush, whichever you are going to do. Transfer the plant back to its grow bucket. I'm doing this with 10 plants individually right now since they are in 3 different flowering areas, I can't use a controller. So I have spare buckets and use them to help change out the reservoirs.

i did the whole bucket next to bucket switcharoo but my closet is only 2 x 3 x 6 feet i think oldmandroman is right i am going to get a pump. one i have seen at home depot hooks up to a drill and you run a piece of hose into the res which runs to the pump and then i will attach another hose to the other end to drain into another empty bucket

flushing is not necessary as plants only absorb nutrients and not chemicals. it has something to do with cell membranes and such. Some good growers here do not flush. If you foliar feed then maybe you should stop that before harvesting.....

so blazinbudsforever if you don't flush can you explain your harvest schedule, like how many days prior to harvest do you just add water, or when to not water at all

I thought part of the idea of flushing was to reset the nutes from a baseline of zero. In other words, when you keep the water it has some nutes in it at a higher level than others because plants don't always use them 1:1:1. So when you add the nute ratio you want, you are adding it to who knows what that is already there.

Flushing is one of those things you can get away with not doing, but its good practice to flush.

do you flush the toilet?

yes i flush my toilet. so i went out and bought a drill pump and a hose. total about 19 bucks at home depot, took the 15 foot hose cut it in half, added a new 5/8 hose thread end, now i have 2 pieces with threads to thread on each side of the pump. then all you do is attach it to your drill and go. it does take a little while to get 4 gallons out. pump is rated at 225 gph. here are some pix
