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.

IPM Advice for outdoor
I'm looking for advice on IPM for my outdoor plants. They've not kicked into flower yet, and I want to be well-prepped beforehand to deal with any bugs that may attack my girls. Here we have thrips, spider mites, aphids and caterpillars mainly. Any input is helpful, thanks! :)

Infected Leaves. To remove part of the leaf or whole leaf?
I had had pests and disease issues my second grow of Autoflowers. I believe it was hemp russet mites which spread disease on parts of many of my leaves. Would it be alright to remove only the part of the leaf that was infected or to remove the entire leaf?

Is it mold?! Help!
Is it mold? These little white hairs in the ground? Soil: BioBizz Light Mix If so, how to eliminate it? Mold has already appeared on top of the soil before. Then I removed it and I've poured fresh soil and cinamon.

Autoflowers with high humidity during night and rot, any solutions for high rh?
Hello everyone, today I woke with a plant rot on some parts, that due to the high humidity it got during the night, 88% and 18 celsius. What are the cheap and effective ways you do to prevent rot? I was thinking of switching from 18/6 to 24/0 but I don´t want to stress them. Thx

Mold on stored coco/worm castings
Hey all, I mixed together 40L of Coco and 10L of worm castings, and left it sitting with a lid. Sure enough, it has some mold growing on the top. Can I still use this medium or should I just throw it out? (Not broke, but cheap!) Thanks

H2O2 bath for light PM on pocorn/trim, pre QWISO?
PM found on trim, post harvest, my bad darnit. *Very light* but I take pride in my work. Personal consumption only. Forums reviewed so lets skip the chatter, will proceed with QWISO. Should I do a H2O2 bath before extraction in ISO? Trim off best plant, Dos Si Do which is strong.

Should I throw a net on her to limit her height or continue LST and leaf tucking? I’m siding with the latter but maybe it will help her in flowering as well if I spread her canopy under a net? Week 5 and showing pre flowering.

My plants are growing tall and fast. If I want to restrict their vertical growth at some point should top them? Is there a time when it is too late to top them and if I do top them will they just become bushy? I did not do this early on, obviously.
