Green in Soil
That70sDude
started grow question 5y ago
I have some green in my soil and I can't tell if its a nutrient or if its Moss, or Algae? I run a cool mist humidifier 24/7 but don't see this on any other plants.

Mold and Harvest time
Hey bros, take a look at the last Day 102 pics, mold... what do you think? Does not smell like it, comes from outside. Looks like a bunch of white pistils together. I've cut one of to examine further with the mic. I will update the pics later. Oh, and also, one more week to go?

Best way to control humidity?
I have a 4 inch inline fan blowing in air at the bottom, I have a 4 inch inline fan sucking air out the top and a 4 inch fan to circulate air inside and a large 300 foot air dehumidifier in the tent but my humidity is still 50%-60% constantly. What am I doing wrong?

What is this white fluff on my grow bag?
I've noticed some white fluff on the side of my grow bag. I'm guessing it's some fungus, should I be concerned at this stage? Day 23 in material bags. Thanks in advance 👌

Mold on soil ?
On day 36 I discovered some strange white stuff on top of the soil in only one pot. Looks like mold and the plant seems not to be infected. Two days ago I gave both of the BioTabs Bactrex and Molasses as scheduled. Does anyone had this issue before ?

white powdery mildew
I think my plant has white powdery mildew, we tried to remove it with a wet cloth and spray with Neem oil but it keeps coming back near the buds and pistils should I cut them or there are other options? We moved the plant to a tent this week with two fans to have airflow.

Fear of mold
Are these signs of mold? The humidity here is very high, the fan is on, but it's complicated. I see no signs of powdery mildew. But could it be some other type of fungus?

Fungi around the seedling
I've noticed some small mushrooms coming out of the soil - I used mycorrhizae around the seed holes, but it's supposed to spread through the roots. There's also some greening on the parts of the soil like bark. Is that a good sign?

Organic growers: question about mold
First picture includes both molds. Second picture is the 'spider-web' mold. (Good mold, correct?) Third picture is the unknown mold. (Is this good or bad mold?) The red wrigglers living in the soil eat mold, but can/should they eat the second mold? Should it be removed?

Possible mold issue
I've had a drastic change in smell... overnight. Smell went from very pungent to an earthy almost musty smell. Could this be a precursor to bud rot? Or is this sometimes normal? Humidity avg 50-55% during day and no higher than 65% at night with constant ventilation/circulation

Solution to height - supercropping, I am thinking, is the only answer? [ or......how close to the lights can the plant get - currently 14" from the LEDs.]

Seedlings are leggy and in a tray under the dome. Dome is cracked open. Using a T5 Reflector. Light is as close to dome as it can go. I have a Viparspectra 900W (R900) LED with a Veg and Flower mode. Env con good. Should I get these leggy bastards under my stronger grow light?

Mám stan 1m² a v něm 9x11L květináče. Po zalití s 10-20% odtokem vody mám problém s vlhkostí vzduchu až 75%RH.Vlhkost mimo stan je 55%. Udělal jsem pro snížení vlhkosti vše (včetně přečtení všech grow questions na toto téma).Otázka je: jak ovlivní menší zálivka výslednou kvalitu?
