Just one quick question before you go, I picked up some 29% hydrogen peroxide, strongest i could find locally, will running this help to prevent disease even if i am fighting water temps a little bit? Just before lights off my water hits 74 degrees, obviously above the 68 recommended and the 72 everyone seems to say to keep it below, but i cannot afford to renovate to fix this problem until the end of this run.

Yes, it'll both reduce pathogens and oxygenate the roots. Presuming you're doing a DWC? Water loses dissolved oxygen as it gets warmer, but H2O2 and an airstone will help.

so i decided to give my h2o2 another whirl tonight @.5ml/gal in a small veg dwc i have. the plants are well established, and im waiting to see if i notice any drooping. i called the chemical company and verified there is no stabilizers in their 35% food grade h2o2, so all should be well.

edited to add:
quite a few other posts ive read say to add it at 2-5 drops per gallon, which would be 1/4ml per gal of 35%. i dont understand why there would be such a large discrepancy between the figures. either way, at a rate of .5ml to a gallon i should be more than fine considering you said i could at 5 or 10 times the amount and it wouldnt hurt my plants... im still shit scared they are gonna get shocked...

.5ml/gal is way too little. For 29% H2O2, it should be about 7ml/gal, reapplied every 3-4 days.

i have to reply to all and zem on this one im sorry guys you dont have to jump on the LED boat but i can tell you from my own side by side experience with the panel and 400w hps i own that the LED panel is most definately better.

With all due respect, you're mistaken. If you have all grow room conditions correct, a 400W HPS lighting an 8 sq ft area will kick any LED system's ass to Mars- and that's a lot of kicking.

5ml/L is not 7ml/L. The dosage I'm suggesting is really quite low- and you're independently electing to take it lower. You're on your own.

kk, if you say its quite low, i will do 7ml, but im using 35% so i lowered it slightly. i will do it tonight, im not saying that h2o2 is harmful to my plants, all im saying is that my last grow i introduced it @2.5ml/g, and within 10 hours my plants were seriously droopy, droopy to the point that some branches fell over and all leaves looked like they had wilt... i had colas laying on my scrog screen, and it looked so bad i didnt take any more pictures of my grow til i was hanging buds up. then i read some people that use 2-5 drops of 35% h2o2 for maintenance in their dwc res. being that i cant find any literature done by universities or such with implicit instructions of using h2o2 it is difficult for me to pour the shit in based off of peoples recommendation. my res runs@65F constantly, i probably have very little to worry about as my res's are very well oxygenated, but im looking for solutions in the near future when i begin growing 10kw+. here is the journal entry as this went down my last grow:

https://www.rollitup.org/grow-journals/348678-600w-dwc-medical-grow-first-22.html#post4833218

so yea, tonight im going to think hard on when im going to test 7ml/g. i may wait as im about 9 days from harvest and could test it at the very ass end of the harvest. the whole purpose of this isnt for fixing an issue now, as i have no biolfilm/fungus/algae/bacteria issue right now. the whole thing is me trying to figure out whats going to be viable for the future and what can be scaled up cost effectively.

edited to add:
also, i did contact the chemical company, and as far as they were concerned their product is safe for use on plants, though on the label it just has directions for foliar application. the FDA does allow for stabilizers in food grade h2o2 in the USA, so there could still be something harmful in there. i may need to just buy some different stuff. all im doing is reporting what happened to me, and why i am so concerned.
 
Hello DR. AL B Fuct, i just want to say thanyou for all your post. i stay up late every night reading your post. Just to let you know, i'm trying to do thing the way you would. My system is a 1000w light system ,blockbuster hood, 40gal rez, 4x4 tent,16pots ,with hydroton, two fans one on the light the other on the filther. just two question, would you use a co2 tank with this setup, and question two, would it be better to grow as a sog or scrog with DNA chocolope? with the 4x4 table i can get around 49 seven inch pots on the table what should i do to get a large amount.
 
WOW, that was all very useful information Al, thanks

I am new and have been absorbing all the information I could here for the last few months and have found it quite conflicting, there is alot of great information but one has to read it all and try to decipher the good from the bullshit, you made it a little easier.

It is nice to hear input from a real world grow vet!

How many ml in a "drop"?

Applying H2O2 directly to a rez where roots are in the solution could have been part of the problem, but this much I'll tell ya- 2.5ml/gal of 35% is about half the efficacious rate for sterilising solutions and would have barely had an effect on microbes, let alone cannabis plants.

being that i cant find any literature done by universities or such with implicit instructions of using h2o2 it is difficult for me to pour the shit in based off of peoples recommendation. my res runs@65F constantly, i probably have very little to worry about as my res's are very well oxygenated, but im looking for solutions in the near future when i begin growing 10kw+.

I take my information mainly from reliable sources such as university studies as well. If you look around on the web a bit, you will find such data. In a quick search, I found this slide presentation on Greenhouse & Nursery Sanitation from Colorado State U: http://ghex.colostate.edu/presentations/Greenhouse_and_Nursery_Sanitation.pdf (see page 55):

Hydrogen peroxide
– H2O2
• Strong oxidizer
– Sold from 3-90%
– 3% as a wound cleaner
– 90% for rocket fuel
• ZeroTol (hydrogen dioxide)
– Contaminated water
• 1:500 dilution
• 540 ppm H2O2
– Clean water
• 1:10,000 dilution
• 27 ppm H2O2
Click to expand...
For 35% H2O2, 2.7ml in 1 gallon H2O = 250ppm; 5.4ml/gal = 500ppm.

I don't know what a "blockbuster hood" is. A 1000 will do very well over a 4'x4' tray- I'd use a 1000 over as much as 20 sq ft. You'll get very good results with the SoG method. I'm not a fan of SCRoG- it's a method intended for a small number of plants and there's some veg time involved. SoG doesn't require any vegging time, no farting around with tying stems down to screens or nets and has much better air circ than SCRoG, with the associated lower potential for mould. Just keep after pruning off the branching in SoG and it'll work well.

Using CO2 is very expensive and requires a grow room specifically built for it, but can be worth your while if you're willing to part with the cash and do the work. To make the best use of CO2, automated control systems which sense the CO2 concentration in the room atmosphere and apply more gas as required are preferred. Application systems which also control fans and aircon are better yet. Mind you, you can easily chuck thousands of dollars into such controllers and you'll have the ongoing expense of CO2 tank rental and hassle of lugging the heavy cylinders around. Combustion based CO2 gens can be used if you have a very large op, but the heat they generate makes them impractical for very small ops like yours.

I don't think I'd recommend Chocolope for SoG. It's a sativa dominant hybrid which has a tendency to get tall. Look around for an indica dominant hybrid instead.

20 drops/ml is a standard although there are a few discrepancies between standards. either way, 2-5 drops isnt even close to an effective dose according to your info. i've already applied 6ml/g and everything seems to be ok. the last run could have been a fluke, or some weird reaction, but my plants were looking just about dead.

just so you know, i never make any adjustments to the water without pumping it out first. all adjustments are made and stable before the water hits the roots.

Something happened that likely wasn't related to the H2O2. Just can't imagine such a low dose of H2O2 doing anything harmful.

What? The wisecrack I made about full-tilt homeopathic kooks a couple of pages back which was much snarkier. :D
 
al b fuct you seem to know your stuff i use the same system as under current systems just a diy version now my question is that when i use just plain water with sensi grow 2 part i have no problems white fuzzy roots etc perfect no problems at all but the second i add any zymes additives i seem to combat problems ie jellysnotty roots etc do i have bad nutes or something an i know it is this as i clean my system trim roots with jelly/snot on an start with just water an sensi 2 part an new white roots appear every where i keep this going for a few weeks no problems add some zymes an bang 2 days later slimey shit covering airstones an jelly blobs on ends of roots so is it bad nutes or is the pathogen just in my system or water supply waiting for its food to arrive i am in the uk water is quite hard around 400ppm i can keep my system water temp at a constant 60-64 degrees i run a 500gph water pump with a 50 litre a min air pump so the water is really areated just wanted some ideas really if nutes were bad or they react different with my water supply in this system

Don't use the 'zymes' additive.

The 'jelly snot' is a mass of pathogens- bacteria, fungi, etc. Dump the tank, clean the tank & airstone. Mix a new tank of nutes with 50% grade H2O2 at 10ml/L. In 3-4 days, dose the tank with 1ml/L 50% grade H2O2 and keep doing so every 3-4 days. Fixed. :)
 
DR. Al, i have 3 questions and anyone can answer this ,1. what do you think about beneficial bacteria ? will it help the plants more or not really needed? 2. do i need a cover for my rez or leave it open/ uncovered.? 3. what is H2o2 and what its for? alge in the rez? always wanting to learn more thankyou
 
Jojo, all of this has been covered in this very thread...i will do my best to give you Al's answers.... 1. He does not use them, anything alive in your system besides your plants is going to cause problems and pathogens. 2. I am pretty sure he said that he does not cover the res, this one i am not positive on but it is in this thread somewhere. 3. The H202 is hydrogen peroxide (not the stuff you get at walmart, that is only 3% concentration and has stabilizers in it that will kill the plants) he uses 50%, trying to find that in the US could possibly get a knock on the door from the ATF. I went to the local hydro shop and found 29% very easy. The hydrogen peroxide is to kill all pathogens and anything living in the res that is not plant material, algea is plant material so the hydrogen peroxide does not affect it.
 
Wow really appreciate that! I know which quote Ill be refering to from now on,lol. Good to know your feelings are the same. Just wasn't sure because like you said you haven't brought them up in ages(August 2008 to be precise). Its good you really broke it all the way down like that for everyone. If they read that and still are convinced the digitals are the best way to go, then fuck em there's just no convinceing them,lol.

I know its not necessary to cut the leaves in half when cloneing but many still do (including me). The reasoning makes since . Do you think it helps clones root quicker or can this just be one less step to not have to fuck with. Only reason I do is because I noticed faster root development when doing so. Could have been a number of factors though water/air(aero cloner) temps fluctuating exc.....

Thanks
 
Hay thanks Trueno man, i'm trying to put in a new panel fuse box set up my grow and go to the hydro store plus get these questions answered so the saleman at the hydro store dont rip me off. so i am a some what newbie but learning. I guess the name of the game is to learn as much as one can and save some money too. we all have to start somewhere thankyou lol

Leave it uncovered.

H2O2 is commonly used in hydroponics as a nute solution steriliser and root oxygenator. In conjunction with inorganic nutes, it's a surefire way to keep rootmasses free of disease and promote root development.

Cutting leaves in half isn't necessary. Leaves are the solar panels for the plant. Once a cutting sets root, it's beneficial to have as much leaf surface in place as possible to promote rapid growth. However, a stem cut isn't a rootmass and there's only so much water a cutting can pick up via the stem cut. I tend to leave 2-3 full fan leaves on each cutting.
 
What's up Al? I got a Question for ya. My well water is 750 PPM in the summer and 950 PPM in the winter. I use a water distiller to make water for my plants. Would you also suggest that I use my well water for hydro or soil as well?
