I suspend (hang) my air pump using some clear aquarium air tube, so that the pump itself is suspended in the air. This really helps with the vibration/noise issues.

I was just doing some more research and I came across this article by Ed Rosenthal: http://www.cannabisculture.com/v2/comment/reply/5417 He recommends drastically higher amounts then I was using, like 1 part per 100 (or 10,000 parts per million!!!!) of H2O2, or 40 ounces of 3% per gallon...

Wow, I'm never going to do a VScrOG again...way too much time to train all the branches and shoots! Anyways, I don't use H2O2 anymore now that I'm able to keep my res temps consistently around 68*F. When I was growing in higher water temperatures I used both 3% and 35%. I generally go by...

Yep, I've read that article before...very good! I have no doubt about the benefits of molasses, even in hydro. I wouldn't use organic nutrients in higher water temps for the same reason I wouldn't use molasses - organic nutrients are meant to attract/grow beneficial bacteria/fungi, which like...

OK, this is fact mixed in with my understanding (or misunderstanding) so take it as you will. As you probably know, the MASS of oxygen (or the maximum amount of oxygen) that can be dissolved in water varies by temperature. The lower the temperature, the higher POTENTIAL DO in the water; the...

I agree with everything you say. HOWEVER...the molasses will not only attract beneficial bacteria/fungi, it will also attract the nasty bacteria/fungi. The beneficials thrive in AEROBIC conditions; the nasties thrive in ANAEROBIC conditions. If you were growing in highly aerobic conditions with...

I agree that a low ph will help prevent pythium. However, I believe the high ph in this case is BECAUSE of the root rot/bacterial slime/dead organic material in the res. These anaerobic microbes release toxic substances that cause the ph to rise. An uncontrollable rise in ph is a sure sign of...

I don't doubt the benefits of molasses, especially in soil grows, where the symbiotic bacteria and fungi help with the uptake of nutrients. I'm not as sure of the benefits in hydro, where nutrient uptake isn't so much of a problem and keeping a sterile environment is important. My main concern...

I would consider it if I was using organic nutes. The main advantage of molasses (at least in my understanding) is that it promotes the growth of beneficial bacteria and fungi, which are crucial when using organic nutes in hydro. I probably wouldn't use it with chemical nutes, especially if I...

I see plenty of threads about specific systems; hell, there's a whole sub-forum for aerogardens. I don't know where you would draw the line; if you grow using a specific system, regardless of whether you bought it from somewhere or built it yourself, you should be able to discuss it. I...

Bonsai, ha! You're on your own with that one...I wouldn't even swear that's a marijuana plant, LOL!

Generally, I would say yes. I believe that the pictures MeisterYo presented are of two different plants. In the first two pictures the overall health of the leaves that you can see don't look good. Unless he's growing a strain like Blueberry I'd be worried about the red stems/veins, and I'd also...

Looks like excessive ph fluxuation and/or ph related nute lockout to me. What's your ph look like like, and do you chase it (constantly add ph up/down to try to keep the ph stable at, say, 5.6)? In a balanced system the ph may drift up or down based on nute usage and will generally stabilize...

Short answer: if you can keep your conditions right (light-proof res, high dissolved oxygen with either low water temps or H2O2 preventative treatments) then the initial cleaning and regular water changes (like once or twice a week, at least initially, to flush dead organic material) should do...

What are the "3 leaves"? The third set of leaves? How old is your plant(s)? Depends on what leaves you are talking about and the overall appearance of your plants. If the leaves are curling in and/or drooping but still green (not yellow or brown or drying out) then your plant MIGHT be...

You can grow with 78* res temps, but you have to be a lot more aggressive with the H2O2 in my opinion. The problem with higher res temps (above 75*) is there's less dissolved oxygen (DO) in the water. Less DO means a more anaerobic condition, and nasties love anaerobic conditions. Your roots...

OK, I got you...the distribution tank is empty at startup and only fills up when/if the outlets can't handle the pump flow. Should work fine...

Also, and I may be high and not seeing this, but what's keeping the water from draining out of the distribution tank into the buckets and then into the reservoir and then your floor, especially when the pumps not running? You may want to connect the outlets from the distribution tank at the top...

Looks like a good design. My only suggestion would be to put a ball valve between the water pump and distribution tank so that you can control the output flow of the pump and prevent overflow if the drain lines can't handle the pump output. Putting the pump on a timer might work to prevent...

Yes, I'm pretty certain that's root rot but get some more opinions before proceeding with my recommendations. In my opinion, if the plants are young then I would start over after thoroughly sterilizing the environment...otherwise, you'll probably be fighting this the entire grow. Pay...
