I'm interested in the mollasses. How much do you give, how do you dilute it and is it better than just water (which is what I do)

yup pure water is flushing thats why i cheat with the molasses as well lol they say its actually 1-0-5 but its non chemical
Nothing is 'non chemical'. If you grow organically and use only water/low dose carbohydrate supplements for the last 2 weeks, I agree that is basically how 'flushing' goes in organics. In most cases there are plenty of/enough nutrients in the soil to last the plant the last couple of weeks. You could always do one last good feeding with a high P fertilizer just a couple weeks before harvest, then finish by giving just water- and the plants will use less water during the last couple weeks. Organics is about feeding the soil. If that is what you've been doing, then the soil and the life within should quite definitely sustain the plant for the final two weeks. There should be mycorrhizal fungi out seeking phosphorous and minerals for you; bacteria decaying organic matter: retaining and releasing nutrients within the rhizosphere- some carrying out specific, specialized processes; protozoa and nematodes consuming those bacteria and fungi to expel more plant available nutrients... maybe even bacteria pulling nitrogen gases from the atmosphere and making them available! If none of this is going on within your soil you aren't growing organically.

There are certain elements that tend to make cannabis smoke harsher; nitrogen, magnesium, zinc, et al. [Most] everyone knows that you are supposed to let your plants exhaust their N late in flowering, too much nitrogen could delay flowering, but it will also make smoke harsher. Uncured cannabis is near-inevitably going to be harsh because of the chlorophyll.

I grow in soil..I was wandering if I really have to flush? I do use nutes..so I always do..but do I really need to?I don't wanna risk root rot..if I don't wat will the result be?


lets say that it took you say ~8weeks to get where you are... why fuck it up now?

[i say flush]

why in the hell is everything in bold now?

coco doesnt hold nutes as long as soil does i do miss my ffof tho so with the coco within 2 weeks tops without nutes all will be gone and than it just will finish out the last few weeks with molasses i actually wanna try my hand at some type of tea since im gonna be runing less plants

I flush. The plant that is being harvested in a matter of days...has had a 3 week flush. (10 week strain)

Everything that is high grade...be it beer, wine, pot or a good bar b q...has steps that need to be taken if one
wants "better than dogshit" results. Now if you are happy with "As Good As Dogshit" then do not follow the steps
of the people that have come before you. Find a single breeder that has won anything anywhere that does not flush.

Why would flushing cause root rot? You only flush for the last 2 or 3 weeks tops. It's not everyday that you flush in that
time period. It's actually a bit less frequent that you would normally water your plant. The excess water flows out the bottom...
just like it would if you watered regularly.

I like to keep it simple. If you have managed to keep your plant relatively healthy up until 2 or 3 weeks from completion...understand
that there is almost nothing you could do besides setting the damn thing on fire...to fuck it up. It's dying already. You just are there to watch.

...In principle you should never have to flush in soil cultivation. It leads to all sorts of complications like waterlogged soil, nutrient run-off, fungus, etc....

Flushing your soil prior to harvest does NOT improve aroma and taste of the buds. It DOES increase chances of getting bud mold within 48 hours and can easily lead to other fungal infections which threaten your crop. The smart way to increase aroma is to buy quality soil and mix it with beneficial aroma enhancers such as worm manure and compost. Rinsing substrates should only be applied to hydroponic cultivations. The idea is to water with a very low EC, special ripening products, or only pure water a few days or a week prior to harvest - again, there should be no need to flush large amounts of water through the system. In coco coir this can also lead to a soggy substrate and increase the risk of bud mold.

so its healthy to not flush non organic chemicals and smoke it ..........ok then Mr
Exactly what chemicals am I smoking dude? The only reason I flush is to remove built up salts, and I mostly avoid that by using Drip Clean throughout the plant's life.

So please let me know Mr Bloom, exactly what dangerous chemicals am I endangering myself and others to?

Which most would agree means water only (in regular/necessary amounts) for the final two weeks. The connotation is a bit different for hydroponics and what some would call 'pseudo-organics'; in which many growers would use a lot more water.

AMS I am not so sure is even a legit seedbank.

I'm doing DWC and I think I'm going to flush using FloraBlend Vegan instead of using just plain water. I figure its better than starving them for 2 weeks.

I use DWC and got some great advice about flushing on this site.......I was advised to only flush 3-5 days......I flushed for 3......those buds are cured up nicely now and are a quite pleasant to smoke.....the ash turn grey/white and the joints stay lit.
worked for me!

I don't flush my organic soil grows. I just water without nutes for the last 1+ week before harvest.
