temp. in closet grow

[TITAN]

I have 3 plants in flower. my temp is never over 72 degrees.

it is around 55-65 at night and 65-72 degrees during the day. is this bad. I found mold in my soil last week and removed it and put in some new soil. well I found it again today.

any help on the mold and temp. would be greatly appreciated

Try using neem extract, that kills mold on soil.

where can you get that? and how do you use it? is my temp change and it being low causing the mold

Let your soil dry out between watering....May also need to cut back on the amount of water...

What light are you using, how big is your space, and are you running an exhaust fan all the time?

[King Bud]

Placing a layer of gravel, to block light to the wet medium, might stop the mold.

you can check out my grow at the below link.

I am using 4 T12's for 12,000 lumens in my closest. my closet is 2ft wide, 5 ft long, and 7 ft height. I am not going for good yield or great quality. just want it to survive. lol I am on my 9th day of flowering .

I just watered yesterday to add my nutes. I am going to let them dry out for 4-5 days

how often do u water

the most important factor that affects the accumulation of mold is humidity. with more light, comes more heat, and therefor, more moisture in the air. addaquit airflow is necessary to remove this moisture. simply haveing an output exhaust "up high" to draw out the hot air is not enough to remove the moist air AWAY from the plants - a separate fan, or series of them, that keeps the air moving in the whole box, especially at the plant, is necessary to alleviate the problem. airflow over/around the plant is also an optimal condition for the plants... the plants "breath" thru the fan leaves (that's why one shouldn't remove them unecessarily - you are taking away it's "lungs") and need the air flow to remove the "exhaust" from these leaves. just like people, they give off moisture when they breath.

but... that's just my opinion :p
