I was only doing frequent res changes cause I am still learning how to amend the res.....but I've been learning how to do that and have not changed out the res since I flipped, if I remember right. Much easier that way and I'm not losing my buffer everytime I change. Yes, bbs and enzymes both. From what I understand Cash, it's the opposite with the chillers. You need them running live to help control the bad bacteria and promote the good. Sterile, as I understand it, one can run much warmer temps cause there are zero bacteria hence, no need for a chiller.
So the reason people run chillers is because thats where water holds the most 02. Its a common trend and from my experiences, is one of the most overrated. Ill just say this, its all in the pheno. My pheno might not do well in your system, and yours might not do well in mine. I would suggest that some phenos require specific conditions to be met, like ph for example. I know for a fact that a specific pheno will run better at a 6.0 ph than a different pheno that will run better at a 5.5. One is stretching more and requiring more calcium, which will uptake easier at a different ph. Like to say that one size fits all, well ill challenge anyone to that argument on any subject. We lack too much info to suggest that anything is the best way.
Like you are on a successful path, my gut is to apply my own criticism, then I realize its pheno specific. Perhaps I could say this with confidence, I would say that with the majority of phenos, there are some variables that are set in stone. That said, the majority of phenos ive seen grown even on here, I dont want them, not even lying. So to me, I hit a brick wall when trying to argue anything anymore.
From what ive read on here, live soil produces more terpy weed. The more bacteria, the better the weed, obv as long as its beneficial bacteria. I would say the lower the temps, the slower the microbial growth. I would rather have warmer water temps to speed up the microbial growth. I want a booming ecosystem in there not a stagnant one. When I increase temps, as long as I keep the 02 levels high enough, theres always enough o2 for my bacteria and my roots. I dont think temperatures decide which bacteria is dominate, I would say conditions would. How much light enters determines what bacteria is promoted. o2 levels are determined by the bacteria and plants combating need for it. As long as you keep a healthy supply the good will still be able to overtake the bad. Now if you cut the o2, even at lower temps, the bad will win. This will also happen at higher temps. Id say the 2 facts we stick with are that microbial growth is discouraged the lower the water temps. Id say 02 levels in water are naturally the highest at 68F, which is what chillers are used for.
Id say that doesnt matter though, that the levels can only be sustained at a set ppm unless venturi injection of 02 or chemical additives. Sure waterfalls other other high aeration methods will work too.
I would say that all the things that people say are good for the root zone, do not need to be done if they are counter productive to other claims. I for one can visually see the slowed veg growth from 72 to 68. Now its prolly a good thing to slow the growth down during flower, cause if you try to push a bud for 6 months, you better make sure your res is just as stable or you will just crash and burn.
I would say there are no pros to running a chiller in a live system, and only cons. Same with the marketing tactics of enzymes and what is best for the root zone. Im quite positive had I a stage and educated audience, this would never be debated again lol. . Oh wait, I do. I just cant even bring myself to use my 12 inch mud knife on my kitchen, dreading the labor. . . let alone spray paint my stage and setup my desk. . lights. .camera. . what in the fucktardation
