Hi guys.... i read up a while ago, when i was in vegatative, that i need to flush my plants near harvest --- but now its been so long that ive forgotten...and im near harvest in a few weeks!!!! So can someone please fill me in on some legitimate info on when to flush your plants near harvest to clear out the taste of ferts etc thanksssssssss
at least two weeks when u get to the 2 week mark u still might want to mature a little longer if so or not its all good just 2 weeks min.
I just started to flush mine - middle of week 5, thinkin, oh I got a coupla weeks at least. This morning I get up and the hairy bits are already starting to turn brown Hope I get to flush a few more b4 its time to chop
dont harvest by the color of the hairs, go by the trichs... and S12 just for another opinion... clean water for 2 weeks before harvest
Don´t worry about it at all godiva, this idea of flushing is total nonsense, a fiction that just gets perpetrated from one generation of growers to the next. The idea is that if you give your plants water only for the last 2 weeks, this will flush out any ferts that the plant has absorbed - I say TOTAL HOKUM. Ferts dissolved in water are absorbed by the roots, then transported up the plant by osmotic pressure to the growing regions, where the ferts become incorporated into the plant´s tissues. The ferts become part of the plant. Simply giving water only is not going to make this process reverse, it is not going to make dissolved ferts go back to the roots and exit the plant. No kind of flushing actually happens. One year I did do this to one plant, just to test my ideas, and guess what, I could detect absolutely no difference in taste whatever between the ´flushed´plant and the others. I defy anyone else to detect any taste difference, there is none. Do tomato growers flush their product? Course they don´t. So do tomatoes taste of horse shit? I don´t think so.
thanks for that.... i'll jst give em straight water and no flush. 3 weeks till harvest....!!!!!!!!!!!!!
Cheers fer that Spanish So would we be as well to continue ferting right up to the end - and will this plumpify buddage that little bit more? (Hark at me worrying about the extra yield when I've already got enough to last me till I hit the old folks home - )
you use straight water in flushing, but thats not flushing... read up on it so i dont have to explain it
Flushing is when you water with large quantities until it runs out of the bottom of the pot so as to "flush" out any nasties in the soil - as opposed to just watering in normal amounts.
The idea of flushing has different applications and only is an issue to consider for indoor grows in (relatively) small pots. Compared to planting outdoors, a 3-gal or 5-gal pot is a tiny amount of soil that can build up nutes, salts, etc especially if the grower is aggresive with feeding. Flushing those out is very helpful earlier in the grow, particularly when switching to flower. At the end of the grow flushing is supposed to enhance the taste of the final product. Spanish, I agree with your overview of nutrient uptake, but I also maintain that plants "eat" nitrogen and will eat their stored supply when you stop feeding, and I do believe that depleting the nitrogen before harvest does improve the taste.
K, so surely it wont hurt at all to flush with 2 weeks remaining, since some people tend to think it helps taste - i have nothing to lose !!! thanks alot fellas. Be sure to check in on my grow log throughout the coming weeks!! - only a few more weeks till harvest, woohooooooooooooooooooooooooo
Have to agree to differ on that one toasty - I appreciate your point, but could detect no difference in taste whatever between a plant that was ´flushed´ and others that were not. And defy anyone else to be able to detect any difference.
spanish when u said what u did about the nute uptake, that makes perfect sense to me. and what toasty said about the nitrogen so what fert can you get that only has P. or would you just have to pick a side to fert or not to fert.
