Need Help!!! Clearex

im flushing and was wondering how long should i wait for the flush to run its course im in a waterfarm thanks for any help.

just give it regular feeding schedule, you have to drain away the water everyday for 3 days to properly flush your plants, keep doing it till the ppm stop rising.

im doing a final flush not just a flush to fix a def. or as a normal flush every month or so... some say its not neccessary but i dont want to smoke harsh ass weed..

the only reason you should flushing monthly is to get rid of any salt deposit "IF" you have any. The final flush is to take out the chemical in your plants and that takes time, therefore 1 wk of flushing with regular water, 3-4 day flushing with clearex. If you think you can just run it through your system once and everything is completely flush then you have no idea what you are talking about and doing.

sorry i thought u was flaming me when you said your doing a final flush.

Well first of all you didn't specify to me what type of hydro system your using hence i told you just give it regular feeding schedule like if u use a ebb-n-flow then flood with the clearex whenever its time to flood, ect. Clearex help the flushing process go faster, so if u was to use plain water you'll flush for a whole wk, if u use clearex 3-4 day before harvest, this gives you that extra 2-3 days of plants being fed with nute.

right on its all good i was just coming on here trying to some helpful info from some hydro gurus and i was expecting to be flammed in no way was i flamming you i was just asking on how long would it take to do a final flush with clearex in a hydro farm sorry about being a little rough with the tounge i was just like what the fuck dude im just asking for some help bro peace and smoke it up

If one of those WaterFarms. I love the little thing. When I do my final flush before harvest, I drain all the nuts and water out and replace it with ph'd water, I also check the PPM of this water with no nuts. I let it run for 24 hours, I then recheck the PPM. It will be like 300-400 higher then original. I then drain and do it again. Rinse and repeat until your ppms do not raise. Should take 3-5 days. I then do 3 days with Clearex.

One other thing with the waterfarm that I did. I hooked a 5 gallon bucket to the water farm with a shut off valve in between. I can drain the water farm now with out having to pick the plant up and off of the base. I then just mix my nuts in the 5 gallon bucket, and when it is all ready, I just open the valve, and half of the 5 gallons flows into the Waterfarm. So much easier.

Hope this answered some of your Question.

right on thanks that sounds like a bad ass idea one of my friends gave me the same idea next go around i will add that but also should i do the whole 3-5 days plain water and then 3 days clearex because heres how i did it... i put plain spring water for 24hrs then i put some clearex in and its been running for about 3 days max give or a take a half a day.... so would i be able to cut down quite a bit of big fans leaves have died off... also would it be about time to chop down with out all the chems to be in there?

those nuts are in the water. you just diluted them. You need to switch out the water at least every other day. not just once.

Ohh wow, I'm glad I read this post. I started flushing at the beginning of week 7 figuring that just running straight up water for two weeks would be a sufficient flush. Didn't even think to check the PPM of the water I put in there. I know it was clean when it went in, but didn't think about how much nutes would come out of the medium.


I'm at the beginning of my last week. Do I need to change my water every other day? That seems like a HUGE hassle. Do I absolutely need to get clearex to flush if I flushed with plain water for 2 weeks?

yeah that should be good enough (just plain water for 2wks)... im using clearex because i put nutes right up almost until harvest this time with some badass phatty nuggets this time... so with the clearex im trying to get it out fast enough to not do any damage to the buds.. as far as changing out the water every other day im not sure i would like some help on this as well seeing that i havent well hopefully some hydro heads will shine some light on this topic...

ok you need to give your plants nutrients to the max so that you can get every last bit of mileage out of them. This is why clearex help because it can flush your plant faster then plain water giving your plants more time to manufacter thc at the end of their life. Hence u flushing 2-1wk with water when you can use clearex the last 3-4 days giving you you that 10-7 day extra for plant growth. A hint you can tell its completely flush when your plants are turning fast, you'll have to make observation everyday and also check the ppm. Mines are always done on day 3 1/2 and i don't give them any extra time of darkness because i want them to work out all their food supplies.

Hope that help if it does Hook me up with a rep =)

when your plants start turning fast what do you mean? start yellowing because quite a couple of fans leaves have died off... majority of the plant thou is still green but a light green not the deep dark green they used to have...

yea as you observe the plant yellowing growth rate, when you flush the plants starts to deplete all the nute so they'll yellow up faster.

Same here. They have lightened up and a few have started showing different deficiency's, but I'm obviously just ignoring them. The buds look good and they have continued to fatten up over the last week.

I'm glad I didn't read this previously. I'm going to do the plain water flush this time and next time I'll use the clearex method. I'll see which produces better and which tastes better.

I'm sort of an experimental type grower. I've done long veg less plants, more plants, less veg, lots of plants no veg, soil vs. hydro, 250w vs 400w. Just like to see what each does.

So far I've found that hydro w/ minimal veg seems to work best for me. 9 weeks from start to finish and w/ 6 plants and a 250w light this time I'm looking @ ~a QP. Not too bad for nine weeks.

Thanks for your help guys, I look forward to next Sat. harvest! Woo hoo!

so the faster they yellow the more better the flush is? or the more that all the chems are out first time using chems i used organics in soil so im not used to the whole flush thing so sorry for noobness but thanks for the help

when they yellow that means that their are feeding off themselves, their using up the food storage in those fan leaves thats why it yellow and die.

yeah cause it means your plant is using up all its nitrogen/nute reserves. just plain water for a week is fine. simple as that and you have the best tasting weed. clerex allows you to use just water and clearex for 4 days instead of a week but i found with final flush i didnt get as nice taste as just water.

so would it hurt if i let it go a little longer with the clearex and plain water or would it have negative effects because im seeing some fattness in the nuggs with in the past couple of days so would i ruin the plant if i let it go for a wk or maybe a few more days?

it won't hurt, but on another note you wouldn't want everything to yellow up(this mean you left it to flush way too long) and also thc degrades and so does everything else at a certain point. Its up to you to decide but thats when you know its flushed when its feeding off themselves.
