Hi Im just about to start my rdwc
ive got some seedling and im going to put them in clay pebbles in net nots above a 90 ltr tray until they are bigger
I will be feeding them by constant dripper. on 18/6 under a 400 mh im going to use canna aqua Any Tips ???
1/ how does H&G root ecxel effect EC ?
2 Do I need to use the cooler with the drippers before the roots hit the water ?

Any advice pls people
many thanks fr:cowboy:

Is the cooler not in the res and the drippers come from the res?

depending on what your water reads without nutes ? if its any lower than 0.4 then start off with 0.5ec and hold it there for a week or so, theres no need to have drippers on 24/7 , every few hours for 15 mins will be fine, just make sure it does,nt splash the plants or you,ll fry them, if you can keep rez temps around 18 degrees then all the better but if its around 22 without chiller then it,ll be fine, the root stimulater shouldnt affect ec too much just add that first then the base nutes

hi drippers come from the res Not sure what you mean about cooler ?

yea you should have the hoses from chiller in the rez and a seperate hose for the dripper coming from rez both on seperate pumps you mean ?

hi My water reads 0.6 EC so I should add the root excel first then take it to 0.8 ?

Murdock
12-08-14, 10:01 PM
yea that sounds fine, give it 0.1 of both to take it to 0.8

My plan was to use the returm from the cooler as a water fall to create DO
Do I need it ? I was told the pebbles allow the young roots to breath unlike submerged RDWC ?

Murdock

the waterfall affect is good but there should be plenty DO if the water is sitting at 18 degrees but it certainly won,t do any harm doing it the way your thinking, you can only do that to 1 pot though yea ?

Freeherber
12-08-14, 10:05 PM
Ah yes !!! Ive got 2 separate little pumps One for the dripps one for the cooler
Going to put one for the cooler outside the res to avoid any heat transfer

I was going to put 6 net pots in there ?

just until they hit the water ....
will that be ok ? can you see any issues ?

Murdock

should be fine mate, just have the bottom 10ml of the pots submerged until you get a few roots through then lower the level to just below bottom of pot

Murdock

i hope your not thinking of vegging long with 6 plants in a tank that size though, they grow at some pace and it would take no time to get overgrown with 6 plants, so a week or 2 veg then flower if i was you

Freeherber
12-08-14, 10:14 PM
I was wondering ???? do clay pebbles actually wick the water/nutes ?

yes its just for a week or 2 until they hit the water then I plan to simply move the net pots into the big system using the exact same conditions I just bough a blue lab guardian so im hoping to be able to control it well

Murdock
12-08-14, 10:18 PM
just make sure they get a really good scrubbing as they can mess your ph up but you,ll only be using them in net pot and they won,t be submerged so you,ll only be using a few, no worries

ah so the 90 litre is just a nursery, sounds like a nice set up, is this your first hydro grow too ?

Hi everyone
Well I have the tank set up and ive put the little ones in the net pots
canna aqua EC 0.9 backround EC 0.7
water temp 19
ph 5.7
I have them on dripper rings being fed 4 times a day for 15 mins they seem to be doing ok.
I have a pump outside the res circulating thru the cooler, this is running 24/7 is this needed ?
I mean the roots are not in the res yet so I could just top feed ?
can I top feed ? and put the cooler on an hour before to cooler is down and add the DO
Any advice ?

Yeh I would keep pump moving the cooler water to make sure its cooling if all

Keep top feeding till u see roots hit the res feed 3 times a day let them dry a little n go searching for water

If u roots are not in the res then the cooler will be ok if fir now but once u hot the res get the cooler on
Hope it helps u

Murdock

yea man , no need to have the chiller on 24/7 but it should,nt be on much if its working within 1 degree of what you set it at, but yea 1/2 hour before pumps come on would work, or just turn it off until roots hit the rez and topfeed a few times a day

Freeherber
17-08-14, 07:47 PM
hello mate i will put it on an hour before and let it waterfull to crate DO then take a jugfull and top feed until the roots hit the water
is that ok ?

Murdock
17-08-14, 07:48 PM
i,d just sit a jug full in a cool place until roots hit rez, there,ll be enough do in cool solution

big Buddha cheese 4 weeks from seed
backround ec 0.6
ec 0.8 canna aqua ritzotonic
4500 ltr pump feeding spray bars in 50 ltr bins
2 600w under parabolics
separate res in another room with a cooler return from cooler flooming back into res
temps stable at 19c
ph starting at 5.6 rising slowly however the ec is not dropping they ssem to be ok but they are yellowing from the top down
not sure if its cal mag def ?
any thoughts anyone ?

FACE
09-09-14, 09:04 PM
Looking nice set up u got and a great big screen
It may take a while to fill but will be worth it
What's your ec at ? Is it rising ? If so drop it a little
U should be ok keeping ec 5.6 to 6.3 they dont look to yellow
U could switch to a 600 mh in the middle to veg them
It keeps them nice n bushy

Freeherber
09-09-14, 09:24 PM
hello mate the ph is 5.8 and stable maybe moving up a point every couple of days
ec is 0.8 and has stayed there since Friday when I put them in the new system perhaps it will drop in a few days
the system holds 170 ltrs.
I have just order some bennies TNC mycorr hydro as ive heard good things about them
how often do I have to put the bennies in ?
any other info that might be usefull this is my first rdwc grow
thanks fr

09-09-14, 10:10 PM
I would lower ec to around 0.4/5 say since u got them in 8
All u do it take some water out your red and top up with plain water checking ec as u go to get it right level
Drop your ph to 5.6 this will help the uptake of more cal / mag in the plants n sort out the yelliw before it gets worse
Bennies once a week to the system is enough
Make sure u got all light leaks sealed around your pots so no light get in at all check for green algae it will show that first
U dont need yo change res e dry week also as this small they won't use much
Get a diary going and u will get hoed along the way a shall pop in see how things going

yes ok thanks for all the advice im going to start a diary this week !!!!
look forward to your wisdom as it develops
