The plants are all in my bubbly tank until harvest. Up till a month ago they got nutes right up until the day I harvested because they were in the pool that has nutes in it. I am in permanent grow style where babies, vegging, and flowering are all in the same nute bath. Then I listened to many who thought a flush was necessary and in some cases even darkness. So I started to take then out of the tank 48 hrs ahead of harvest and put them into a pail of plain water and put them in the dark. I honest to God can't see, smell or notice in the smoke anything at all different between the rinsed ones and the unrinsed. Next I am going to take the next ones out a week ahead of harvest and put them in a pail of plain water for a week before I harvest them cause some say 48 hours isn't enough. I will try that and see if I notice any difference.
I have a second grow room where the photos go. I used to switch nutrients from vegging to flower but this year half the photos are not getting different nutrients from veg to flower and the second half is just to see if I can notice any difference in groth, bud weight, smoke and flavor. It would be nice if I could notice a difference then I would feel justified with the bother. If I still can't notice any difference then I am going to give up changing nuits and rinsing completely.
My wife grows organically and uses fish emulsion and Iguana Juice I can smell that stuff in the pot as it has a faint rotten fish smell. When she rinses I can still smell the fish in the pot. I don't smoke her organic stuff. She has a friend who says she is wicked sensitive to chemicals. Last week she smoked mine and commented how clean it tasted and how fragrent it was. I just nodded and smiled.
