    Ozone Levels To Kill PM?

    I've been battling a pm problem. * I have great ventilation. In fact, it's way overkill. * Humidity has been super low so far. Not an issue. * I'm increasing the # of circulation fans in the room. I notice that the pm only grows on the side of a plant that is facing away from the...

    About to start using Potassium Bicarbonate

    Hey all, I'm about to start using Potassium Bicarbonate to control PM on both my mum's and flowering plants. I've read that it can be applied right up to last day before harvest. Doing a quick search on here just now, I read that it will burn the hell out of the hairs/pistols. This sounds...

    Repurposed couch cushons, or new growing medium?

    Hey all, I've had it with using rockwool cubed for my cuttings. I can't always be home every 12 hours to do the watering, so my stuff is always either too dry or too wet. Either way, it translates to dead clippings with no roots. Searching for a open cell foam to use instead. I'm looking for...

    Plants reverting back to veg. Bummed!

    I had to get my plants out of the garage and tear down my setup for an inspection a few weeks ago, so I brought them up onto the patio. They were about done under my light in the garage, but now are sprouting new growth. I pulled them half way threw week 8 of 12/12. The daylight this time of...

    GHP PH Up & Down Cause Nute Burn?

    Hey all, I'm on the last two weeks of a 8 week flower in my hydro system. I'm following the Al B. Fuct plan and trying to replicate his techniques. I just changed my rez and nutes, but messed up & added too big of a splash of JHP PH Down to correct it. Then I had to add some GHP Up to...

    Media free net pot E&F/F&D?

    Hey all. Noob here. I know someone is doing it this way, but I can't find an example doing a forum search. What I'm thinking about is a net pot setup without any media. It would only be using the STG 2" rooting cubes in 2" net pots (so not actually 100% media free if you consider the STG...
