yea. you dont want your nute soltion to see light at any piont. due to the nutes in it, it will grow algae real fast.
Water Temps=important Summer=warm

not always... I've flowered these plants like this for 10 weeks now, roots and res exposed to light the whole time and havent had any problems. I use GH 3 part nutrients and h202 though, not sure if that's what makes the difference. It could be a very different story if I was using organic nutes.

the h202 kills all the algae before it can form and cause i problem

But it also kills off all the beneficial bacteria as well.
true. so I guess the best way to go about it is to keep light away from the water the best you can, then only use as much h2o2 as you need to prevent any algae from growing.
I believe that beneficial bacteria are for organic nutrient grows.
if you're not dealing with organics... then beneficial bacteria is neither here nor there.. h202 kills all the undesireables.
I switched to this because of Al B.... and i'm very glad I did, the more simple everything is, the easier my life is.

Beneficial bacteria are good for both chemical and organic growing. Saying they are only useful for organic growing is like saying exercising is only good if you are eating healthy. Exercise is good for you no matter what you are eating, just like the beneficail bacteria are good no matter what you are growing with, organic, chemical, hydro, soil , etc.
Instead of using the H2O2, try using Sub Culture. It will kill off the bad stuff, but actually adds good stuff to the water as well.

he is right. as much as i respect Al. B cause he is right about alot of things... I would go for the sub-culture. I works great. but you have to use one or the other you cant put h2o2 in a solution that has sub-culture.
I'm no expert, by any means.... I'm just saying what works for me, or better yet, what HAS worked for me so far. I got an excellent harvest w/out beneficial bacteria... I dont know what subculture costs, I just know that simplicity is what I need to keep everything under control as best as I can. simply put, I want the most simple application possible.
I've had my fair share of trial and error, and.... now that I have something that works from start to finish, I'm a bit sketchy on trying something new. I've had many failures, (most due to inexperience, and a few due to stupidity) and I'm not saying that subculture isnt awesome... I'm just saying that I'm too chicken to try anything other than what I've stumbled upon that is working for me now.
I never mean for any of my posts to be taken as gospel... just a little insight to my brief experience. The same way that I would disuade any beginner from dumping molasses into his rez... yeah, some have done it with fine results... but it fucked me up, not just once... but twice (the stupid part).
I will read up about subculture, but... root rot is something that I never want to mess with again, it's been a losing battle for me most of the time. to me, h202 is my savior.

agreed. I def understand where you are coming from yak. Not only do i understand it but i respect it. You are absolutly right on the situation. I feel the same way with subculture. I found somthing that works and am afraid to change in fear of another collapse due to my error. And like you I have seen the nasty sugar ball that gets created by too much mollases! Unfurtunatly I wouldnt be as knowledgable as I am without the expirience. But all in all i think that all of use prove that is many great ways to tackle the root rot issue.
Also what is you method for H2o2. I wiould def love to try on a separate grow or sep rez and see the dif if there is one. I also use GH flora series and would love to know you mixture! Thanks again for your time

no prob! my mixture consists of .... GH Flora, micro, and grow, I typically use them at about 2/3's to 3/4 strength, i have never used them full strength. I also add SM90... a while back someone suggested that it'd help prevent root rot, and I just really like the smell of it, it's like an oil. I like the stuff, and it's not too expensive, so I use it. last but not least, I use h2o2 @ 1 tsp per gallon when I do a res change, then, every 3 days, I add it at 1.7ml per gallon.
that's it. super simple, and I could probably do without the SM90.... but I f'n love the smell of it! weak ass reason to use it I know... but ... I dont care.
One more thing, flood and drain is WAY more forgiving of res temps than aero/nft is! I thought I lost my plants to rott, I put them in flood and drain, and all is well. Strange, and great.
this is a great thread, and winter is coming, thank GOD!

If you call adding something every 3 days easy, than you would love the Sub Culture. You only add it during your res change, and you're done.
If you never change your growing methods, or try something new, you will never get better. You will keep acheiving the same results over and over again. And while they may seem great now, with a little tweak here and a change there, things could be way better and much easier.

Cool, thanks yak. i am def going to eventually try things like this . I actually use a DWC stand alone bucket system. the res is recirculating so i think the h2o2 method would work well in it. I had never heard of SM90 and will have to check it out. One other thing though..... do you use store bought H2o2 or do you buy the 49% horticulture kind from shops?
.......THANK GOD FOR WINTER IS RIGHT
here in pa (not sure if it's different elsewhere) my local grow shop doesn't carry anything over 35%. he said 35% is food grade and it's the strongest he can sell without special licensing. just a quick bit of info.
I've been told it would be cheaper for me to buy 35% h2o2 and use less of it at a time, but I've just been buying a bottle or 2 a month of 3%, and adding about 3tsp to a 5 gallon res every few days. $2 a month from any grocery store, rather then $12 from a grow shop probably once a year. actually.. I just did a really rough calculation, and it turned out to be the same price either way. you use 11.6 times as much with the 3%, but the price turns out to be very close in the end either way you go.

does the 3% have the same effects thogh as the 35% or since you are using more does it level out?
I think the filler is just water. dilute 35% h2o2 with water 10 to 1 and you have 3%. buying normal 3% has been working for me and works for many others. the price difference was the main selling point for the guy at the grow shop, but my rough figures show it's the same price in the end. maybe someone else can point out a benefit, but right now, I don't see any difference between using 3% and 35%.

Yea. thats kinda what i figured. It is much easier to get froma drug store then having to go all the way to a local shop. not to mention that if it is the same exact thing and does the trick just as well then there is no reason to get the "fancy" H2o2

maybe someone out there knows a benefit to using the horticulture h2o2 cause i would love to know
