thats what im using right now in my flo n gro. ill keep u posted how it goes if u want. i started with clones in the system cause i had two other strains but one getts to tall to keep them even but i plan to flip them to 12/12 in a week or so. oh i got some airstones running as of today will see how that goes next im goin to get some h2o2
 
how often are you flooding? I flood x3 a day each flood is 30min.
my floods dont change for veg or bloom. and how much prep to
stablize ph do you have to do?

i guess u r suposed to soak the small cubes for a few seconds in 5.5 ph water but the bigger blocks i think its like 15 min. thats what the video said. i didnt soak mine and my ph moves from 5.8 to 6.1 after a few days
 
DSCF3133.jpgDSCF3137.jpgi use the sunleave grow rocks,their fired shale,they only need to be rinsed once,and are ph neutral,i put it in 6in nets,i cut a 6in hole in the 3gal bucket lid,and the roots just hang down from the bottom of the nets,(unrestricted for growth) and for an oxygen kicker i put a small airstone at the bottom of each bucket in the water that remains in the bucket,as well as two large airstones in the res, they get a bubble flood 4 times a cycle,they love it! the rocks are very easy to reuse,a quick rinse in the net pot and their ready to go again,i use less rock,less cleaning,less weight,kind of a dwc/ebb and gro/bubble bucket (excuse the quality of pics,but it will give ya the idea)
and folgers coffee lids fit over the pots perfect lol

Hellraiser should remember the heated debate with kitty about this.

I use the 6x6 rw cubes and it works great. Clones to a rw starter cube and then into the 6x6 for a couple week veg in a tray then they are set into bucket. Way easier then hydroton. Just as cheap and alot less labor. Specially when your runnin 80 to a setup.

I flood for 15 min 1 hour after lights on and 3 hours before lights off. I am going to experiment with 1 flood a day at high noon and see how that does.

One thing i would recomend is a chiller for ur rez.

Peace

lol I remember a bunch of heated debates with kitty guess the kitty got ran over!
 
Its a water content thing. If there is enough moisture for the roots then why water so much. It seems as there is not as much evaporation in the buckets compared to a tray.

Grodan has a multi meter that checks the wc the ec and the ph from inside the rw. Im still trying to get more info and pricing on it.

I read a great article on some forum (i think i saved it in favorites. Ill find and post) but if i remember corectly it was all about how the ph is a lot higher in the rw, so a lower ph than usual should be kept in the rez, and also a lower ph in the pre soak water.

Here is the link to the meter http://www.grodan.com/solutions/water+content+meter/wcm-+control

Cannot find the article about ph and rw but i have been keeping my ph lower than usual and it seems as though the plants are greener.
 
med4u how many grows have u used the sunleave grow rocks? i got a sample of it when i bought my flo n gro system it also came with some kind of a bag that holds the rock in the bucket im guessing to keep the small chuncks out of the pumps.

i went with rockwool for the same reasons of washing the clay and it seems like a lot of work to prep them. ill pre soak my 6 in rockwool for 15 min in 5.5 ph. my buckets r a lilttle bigger than the cap system so next time im goin to use the small grow cubes or curtons as hellraizer called them on the bottom and the 6 in on top and see how that goes

i have used the same rock for 3 different grows,the ones i use are 3/4in and have had no problems with them falling through the net pots as the slits are very narrow,not familiar with the bags,something new,or just for sample maybe,i have read the main concern with hydroton is that after a few use's they tend to absorb pathogens since they are porous,as it was explained,after a few use's break one of them open and you can see what has been absorbed,even after rinsing

i also tried the stg,dont bother its crap
