Hydroponics

i'm not a dwc expert so i encourage anyone that knows better to correct anything i might say that is wrong....

i know that you want to keep the rockwool moist, but not dripping all the time.
but its to my understanding once the roots come out of the rockwool and they are in hydroton i would think a constant 24/7 water would be ok.
also to my understanding, the roots can touch the water as long as there is space between the water and the net pots for the roots to have air i imagine they will thrive.

I'm not an expert either, but Roseman is, and he says 24/7 is fine all the time, as long as it is a very light trickle. Once the roots touch the water u can take out the feeding tubes. Once the roots get closer to the bottom of the rez u can unplug and take out the water pump and manifold so the roots dont get sucked in and burn up ur pump. There should be about 2 inches of space between the bottom of the net pots and the top of the water. The spray from the airstones should wet the hydroten, but not soak it. :blsmoke:

Can someboudy walk me though how to top my plants help

its quite simple actually.
just cut the main stem at the newest growth/node(the very very top).
then you can either try to root that cutting you just cut or throw it away.

wait 10 days to 2 weeks after you do this before you flower or take more clones.

It is ideal to do them when they are still small. You want to cut them between the second and third node if you can, but if that means that u cut off alot of plant just do it where u can. The point of topping between the second and third node is that it will cause the plant to have 4 main colas instead of 1. Topping it later in the vegging cycle is done primarily to keep the plant shorter and bushier.
 
I can't actually read through 127 pages so sorry if this has already been asked :)

but does anyone have any experience using an nft system, I'm a 1st time grower and already got it all set up.... probably not the cleverest of ideas but hey i liked the idea XD

you can look at my lil journal thing for a picture, i think its in my sig but atm im still germinating my seeds.

thanks!
 
Does anyone know how often to feed the plants during flowering. Sorry if this has been brought up in this thread, but I too do not want to read 127 pages. Quickly on my system: I have a bucket-drain ebb and flo system that is controlled by one resi and a brain going to the different buckets. Our medium is hydroton clay pellets on the bottom half of the buckets and rockwool cubes on the top half. When we feed the brain pumps the nutrients for an hour and then drains. My nutrients and pH is good, but how often should I feed. I have read that you should feed 2 or 3 times a day with the system I have.
My friend and I are arguing about when we should feed. We both agree that we should only feed while the lights are on and that we should feed first right when they wake up for their 12-hour day. He believes we should feed again three hours later so the roots have about 8 hours left to dry out in the light (to avoid root rot). I believe that we should spread out the 2nd feed to about 6 hrs after the first to dry out the roots inbetween the two feeds. We are both new to growing for the most part and an advanced growing opinion would be great!
 
I read this entire thread before I planted anything! Some of it I read more than once. thanks to Joker209 for all the help and the rest of the fine ppl on here. latest update.
I'm a spacey bastard I guess. I kept forgetting where I found info at so I did a lot of reading. My biggest problem was white slime!!!!!! I had three tubs with 12 3" cups in each. most of those had 2 plants in each cup. I was testing vegtables as I tend to kill plants just by looking at them. I eventually lost half of the plants to the slime because I kept missing the part about using hydrogen peroxide. No hydro stores around where I live so I just bought the store 3% stuff. I dumped a quart in each res & sprayed off the roots. I won't forget all the lessons I learned from my experiences! I feel confident that I could try a single plant grow. I say single because if I space it or fuck it up I would only lose 1 plant. they are too expensive to waste, that's for sure.
It's too easy to grow in a bubbler now that I have a good understanding of it.
Take the time & read the thread! just a couple of pages a day it is worth the time! It will save you time & money in the long run, unless of course your hard headed & forgetfull like me. Also read Al B's threads.
 
fair play :) I have read a shed load of stuff over the past couple of months and since I posted that I've been slowly trawling through this thread... very slowly mind you.

your not wrong though they are too expensive to fuck up, learning from doing is a good way of finding stuff out as well though, why im practicing with bag seed XD
 
I've read almost all of this thread, and almost every thread pertaining to the instances I have in my place. I really just want to know the benefits or disadvantages of different watering cycles. Right now I've got them on 15 on 15 off in strictly hydroton, about 14 days into flowering. They're 28" tall, ak48. I'm not really having problems with the plants per say, just tall humidity readings. Could I move that number in different directions and see benefits of lower humidity while continuing to feed my ladies correctly. Any viable input would be greatly appreciated. I know I've left out alot of details. I'm on a need to know basis, and this is all I need to know. When everything finished there will be a full journal. Thanks guys and gals.

No prob at all thanks for even takin time to help me out. Thats what i had thought the day i posted my first post on this thread i just lifted the lights up just to lift up a lil and i went back to my grow see and it seems they've stopped yellowing at least for now so thanks on that one. Becuz i think the orverall temp of the grow room is ok 80f. and there is a constant flow of intake and exhaust with the intake at the bottom blowing right next the plants. I plan on getting a ac/dehumidifier since by the time i get to flowering I will have 3000 wats of light going but as far as vegging go for right now 1000 will be enough. the hydro feed schedule is 3 times a day 8 hour intervals 2 intervals feed them for 30 mins and 1 for 15 min. no special technique in coming up with the feeding sched but since i got those clones lookin like mini bonsai trees in a cup they have really exploded since i put them in there so the schedule isnt bad but if anyone has any suggestions like add an extra interval or cut the feeding time from 30 to 15 mins i am all open but would like a lil explainin on why. As far as the o2 goes i have an air pump with an bar airstone that i have not put in yet. also i'm not to sure but will cutting time time from 30 to 15 mins help at all. yea there gettin less nutes in water but i heard that they didn't need to be saturated for that long. Anyway I really appreciate the help and would appreciate any other help with any other probs i may have. Once again greatly appereciated and thanks.

Actually I know you've heard the terms of "Dialing it in" correct? This actually refers to what you're asking about the on off schedules. Best way to test is run it for half a day with different intervals until the plant looks like it's growing it's best and keep it right where it's at for a while until the plant want's more. Dial it in :D Good luck man keep us updated

Hi I am on my first proper grow where I am trying to do everything by the book. I only recently joined this site and I'm glad I have because its a very useful site (Y) :D. I am only 2 days away from harvest atm and haven't made a journal but i will on my next crop.

I have many questions to ask but I won't ask um all now. Q1. How often would you change the water in a flood and drain system for the flushing stage (I'm flushing for 12 days by the way). Q2. is there anything wrong with putting different strains in the system as they all feed off of the same water (do different strains need different nutes). Q3. If 1 plant has not fully matured yet but all the others have (Remembering they are all in the same system) Can I flush for the time I have to and then put nutes back in after the flush and harvest of the rest of the plants. So i can keep the other plant till its ready or should i just chop um all at the same time.

I take it no1 wants to answer my questions hummm quite disappointed :(
 
Wat up potroast, I am new to using forums so I dont really now the ins and outs of using a forum. But Im building an 18 gallon six site rubbermaid hydro-set up I just dont know what to go with Bubbleponic method vs. aeroponic, If I use Bubbleponics will the tub wilt due to the water weight? my net cups are two inch. If I use areo setup I just dont want water to spray out of the container. But its my first attept. I have PVC pipe, and 6in long air stones I just need help deciding.
 
I have a supercloset superflower hydro box.i am 6 weeks 5 days into bud and one of my plans leaves went completely yellow in 24hrs.why ?and what do i do to save?only one plant is doing this.I change every week,and am using general hydroponics Maxi grow.and Ph everytime

All right! Hydroponics is what I know, and hydroponics is the way I grow! :bigjoint:

This forum will be great, we can discuss anything hydro. No dirtbags here, We haul water!

We can compare the different nutrient salts, and all of the additives. Plus the kinds of soilless media and what irrigation system is best for each. And of course, pH and TDS measuring equipment, feeding and flushing, etc.

And all the while, we'll make fun of those guys hauling big bags of dirt! :blsmoke:


I can't think of any questions right now, what do YOU want to know?

Cheers Potroast! Good to meet a fellow water hauler. I have 12 plants in one of those blue kiddie pools...running a aero/fog set up. how would you go about distributing the nutrient tea (in res)? And did I mention I'm doing a vert-setup with 2000w in a diy cooltubes. Im having trouble fully seeing it through in my head :confused:. Your experienced advice is always respected and appreciated. Thanks Potroast.
