    1. Myth Busting - Autoflowers Revegging (can autoflowers reveg? Give us your thoughts!)

    Come give us your thoughts; we want to hear from you!
  • We're looking for grower submissions for any autoflowers that they have had tested by a lab or using a home testing device. The idea is to create a grouping of tests that we can use a resource to show growers (both new and experienced) what kind of cannabinoids and terpenes some of the strains we're growing are testing out with!

    Appreciate any help and consideration! Click here for the thread!

Great Debate - Flush or not Flush before harvest?

Once my container grown plants in soil get big enough to handle full watering's, I typically do 20% runoff which is doing some mini-flushes along the way. I'll add that I use Advanced Nutrients pH Perfect nutes that are chelated to help balance the pH and nutrients preventing lockout. I have flushed before during the grow, but this is to flush a salt buildup to prevent toxicity in the soil.

Some folks always flush before a harvest - but I cant seem to figure out why? Are minerals and nutrients that are inside the tissues of the plant likely to be pulled out of the plant by a flush? And why would we want to rob the plant of its nutrients immediately before harvest when adding bud weight is most critical. Seems the plant needs nutes the most at this point.

I have done with great success: Water the plant AND feed, close up tent and do a total lights off for 36-48 hours, then take plant out of tent and harvest. I have done this method for some time now, and when cured carefully, I get the best, smoothest smoke with no harshness as supposedly is the reason to flush at harvest to begin with.

BUT, I am not a know-it-all and very open to suggestions. If I'm missing something, please fill me in. I really want to learn if there is something I need to change for the better.

Thanks.

I am from the camp of no flush & no dark period. I found no discernible difference in flush/dark and thus am not compelled to do so again.

The only thing I have noticed is when feeding MC right before chop its a bit harsh. Not bad but a lot better with a few RO waterings.

Some people can taste the difference, some people can't.

It's a neverending debate that boils down to personal preference.

I dont know if it still holds true but as of 2 years ago (the last time I was foolish enough to post in a flush or no flush thread) no unflushed plant had ever won a cup competition.

I can taste the difference, so I flush, even when growing organic.

And the old dark period trick is for Indica... not just weed in general... it kicks in couchlock on indica strains.

Glad you mentioned the effects of a dark period. I have noted the dark period accelerates ripening and ambering of the trichs which in essence may potentially be the basis of the couchlock effect. Very good point and very helpful indeed. Thank you!
