If ectomycorhrizae are not beneficial to cannabis, why is it in piranha, a plant specific product by advanced nutrients?

Dyna grows pro-tekt is really concentrated as you stated on the previous page, where you suggest an initial rate of .5ml/gal. This seems about appropriate for clones, 3ml may be too much; also be careful as it will raise the ph significantly.

Also I'm running co2 and as such my temps average around 84f, which I believe has helped keep the problem at bay. Should I increase the temps further? I have plants in several different stages in the same room.

Hey I have a big lady with a little bit of powdew forming mainly at the base and stem of some of my yellowing leaves. I'm six weeks into flowering, and so far I've pretty much just been removing infected leaves as I find them. I was considering using a light spray with diluted milk, and...

foreground is a single casey jones, in the background in a chem dog 4. not visible, a purple kush is also in the room under 2k hps via raptor hoods. AN Conniseur base, nirvana, big bud, bud candy, protekt, calmag plus, mollasses, cannazyme in 50/50 coco/ffof. this is a little over 5 weeks...

Looks good!! As stated its difficult to judge even the colors of the pistils with the hps on in a picture. Looking at the trichomes is definitely the best method of determining ripeness. These are at 6 weeks

Doesn't the air flowing from your central a/c into your 'sealed' room displace the co2 enriched air? Dual hose portable ac's are designed to eliminate negative pressure by using outdoor air to cool the core. The question is how well do they work. Would anyone care to share results with their...

I use air cooled hoods in a sealed room and use a 14,000 btu dual hose model to cool two separate tents in a bedroom 12X12 with 4000 watts of light. Outside the tents can easily be kept at 61f, which allows me to easily control the temp inside the tents via circulation fans. I don't know what...

what were your results testertruck?

not necessary. the o2 in air is about 19%,i.e. 190,000 ppm, the plants only use a small fraction of that and anyhow they actually generate o2, as you might remember from grade school. the co2 however is naturally at 300ppm and therefore can become depleted easily.

for the rest of us who live in the 90% of the inhabited world that experiences uncomfortably hot temps in the summer, hopefully my post is helpful.

After doing some more research, I learned that increased temperatures also allow increased CO2 uptake because at higher temps, the plants need to transpire more water to stay cool, so they open their stomata wider and therefore can get more CO2. Increased humidity also helps because it makes it...

Temperature is proportional to the root mean square velocity of the molecules, be it the plant or the air. This means at higher temperatures the molecules are moving faster, and therefore chemical processes happen at accelerated rates, especially diffusion driven biological processes. Even the...

my system is closed. Its the only way I can keep the ladies cool while keeping the intensity right, plus that way they can use extra intensity because of the co2 concentration, I use about 65 watts/ft^2. In the summer there's no way to keep a room cool without ac. If you vent a bunch of air...

250% though? I'm thinking something like 130% might be the maximum increase in growth rate for co2.

So don't use gravity, or just don't reuse the medium?

never expect to not get bugs

bump ....yeah

tablespoons or teaspoons?

Medium, lighting, plant stage/age, what kind of nutes/how much, temps, pictures of whole plant?
