A lot of the good strains are lost in the hype of marketing anymore.

Damm skippy your on the right track,the farther along you go with flood n drain the more you will despise using any type medium,the shits a mess,a bitch to clean,a bitch to lug around ect.
Im an old fart & lifting heavy shit isnt my scene,same with cleaning filthy shit im not some cleaning hag who digs cleaning rocks that smell like sewer foder so i stopped using any medium at all & have the best results so far.
My table is empty,then i stretch the plastic over it with a few xtra inches on all sides,clamp one side with little spring clamps & pull that baby tight from the other side & clamp,makes the plastic tight as a snare drum skin.
When i chop i blow the top of the table with an air wand so no debris gets into the table & when i uncover the table its an awesome sight,roots 12 inches long minimum & white as snow,the best part is if you leave the pumps going till you clean the table so the roots stay wet cleaning takes about 15 minutes.
Try & get away from mediums as ive seen only negatives with all mediums,with no medium all you have to do is increase flood times & your done,no other changes from standard flood n drain.

...the more air in your res the better, but I use those cheap 6" blue strips sold at walmart in the pet/fish area....I put 2-6" strips in each 40 gallon res..... I also use the whisper pumps sold in their fish isle....alot of oxygen will be mixed in your water as the table floods/drains, along with H2O2 in there....my tables=1T4ADFA_en___US452&q=fox+farm%27s+large+perlite#q=fox+farm's+large+perlite&hl=en&rlz=1T4ADFA_en___US452&prmd=imvns&source=univ&tbm=shop&tbo=u&sa=X&ei=QuKdTpWsE4rCsQK4yLSDCg&ved=0CDAQrQQ&bav=on.2,or.r_gc.r_pw.,cf.osb&fp=3fef7adf3901cf7e&biw=1440&bih=733"]http://www.google.com/search?sourceid=navclient&ie=UTF-8&rlz=1T4ADFA_en___US452&q=fox+farm%27s+large+perlite#q=fox+farm's+large+perlite&hl=en&rlz=1T4ADFA_en___US452&prmd=imvns&source=univ&tbm=

Thanks for the link I would love to find some of that big chunky stuff. Looks like it would provide alot more air and stay in the pots well .
Are you using any h202 ? I know al uses 1 ml per liter of 50% grade. But I can only get 29% so I would have to use 1.7 ml per liter Which would be over 255ml every 3 days! Over 1 liter every 2 weeks for 1 res. That seems a bit much.
....yeap, I use h2o2....I use the 30%, and I typically only add a ml per gallon. I try to stay focused on res temps and bubbles in the res also.
H2O2 is water with a diatomic oxygen molecule. It's basically just an extra atom of O2. If something makes a demand on it, like the plant, it will give up the extra atom of O2, leaving plain water.
you have a chiller for the res? what temp do you keep it at?
H202 disapates by the third day of being put in the water
its...I don't have a chiller, my res sits on a basement floor and my temps always stay below 70 in the res.......the main reason for the H2O2 is to kill pathogens....I keep the light out of my res, I add plenty of bubbles, and H2O2....no brown slim. H2o2 disapates quickly and must be added every 3-4 days just as HR30 said....also, as Potpimp mentioned, the oxygen moecules will attach to the pathogens (killing them)...Al has gone pretty deep into detail about H2O2 somewhere in one of his threads, if I find the time, I'll quote his words....
its doesn't ever "leave" it just changes back to water, sort of the same thing that ozone does with bad smells. It just gets used up, and needs to be replaced.
Water is H2O, so it is 33% oxygen always. (333,333 ppm).
Hydrogen Peroxide is H2O2, so it is 50% oxygen (500,000 ppm).
So by adding a little h202 you are not really adding much oxygen at all. You are adding hydrogen peroxide which works to kill pathogens, not increase the level of oxygen in the water.
The reason for using H2O2 has very little if nothing to do with oxygen at all, simply the effects of adding a sterilizing agent.
you just want to argue?
