    Will overwatered damage plants recover?

    2 out of 4 of my plants were damaged from overwatering. All the classic signs, leaves curled under & discoloration. My first time overwatering lol I'm about to transplant the healthy plants, should I bother transplanting the overwatered ones? Will they usually bounce back? Or should I just...

    Is this discoloration normal?

    Seems to be pretty uniformly on all of my plants the Stem discoloration. One plant (back left) seemed droopy this morning, so that's the only reason I even noticed. 12 day old seedlings (NL #1) :-) Lots of pictures, what do ya think?

    Neem Spray vs Concentrate

    Can you spray this spray bottle "ready to use" neem stuff right on top of your soil for IPM, or does it need to be diluted? I've seen people saying dilute but is that for concentrates of neem? Thanks!

    Air Filtering systems. What do you use & when?

    I've been gifted this $699 tower monstrosity (iAdaptAir) with UV lamp. Supposedly it stops or kills mold/pathogens & bacteria. Oh even viruses to 0.3micron (suuure). Now the filters are $125, crazy. So I only plan on using it in my grow room occasionally or when its most needed. If that's...

    Mount for Clip-On fan?

    Alright so my clip-on fans are causing seams to rip on corner of tent. The tiny amount of pressure is too much for my $180 tent, haha. Anyone here devised a homemade "mount" that keeps the clip/pressure off your Mylar? I'd rather not spend $25 on etsy for some 3d printed junk plastic.

    I'm just curious if the power cords etc. laying/leaning on a light could be an issue? I haven't really seen it discussed before. Is my current setup a problem? Whats your protocol?

    Proper clip-on-fan placement?

    I only have one plant left right now in a 4x4. I have a single 6" hurricane clip-on fan clipped to a t-bar on the ceiling, way up above my light. It's set on 1 (out of 2) & pointed downward at the plant... creating a constant gentle breeze on plant. What is your preferred placement area & do...

    What is your IDEAL temperature range.

    In a grow tent, LED, without co2. I've seen those on here that say 75-80F, 77-81F, 80-85F. Opinion seems to vary wildly. If you could control your temperature perfectly whats your ideal # during daytime & nighttime. Flower vs Veg difference? Side note: Ideal humidity?
