    humidity spikes with AC cycle

    I’ve been working on dialing in my bloom room environment. I’ve got mostly everything really steady except my rh. The problem is the rh swings 10%-12% when the A/C kicks on. The temp stays pretty much constant, it’s just the rh that’s the problem. Heres my set up: I’m in a basement 7 1000w de...

    Help improve my grow box

    I built a stealth grow box out of an old filing cabinet (a rather smaller sized one as it’s a stealth box. It measures 18”w x 28”d x 60”h). I started by removing all the drawers, and roller tracks so it was just the metal shell of the filing cabinet. I then removed the faces of the drawers and...

    Mould resistant strains. Advice needed

    Hey guys. I've been growing indoor/outdoor for many years now with varied success. My success is in the hands of the elements as I grow in a very warm environment (up to 40°C) that gets a good rainfall, thus can get extremely humid (Northern NSW, Australia).

    Is strictly exhausted Dehumidifier air good for plants?

    This might be a weird question but is just exhausted dehumidifier air good for plants? Long story short as possible, I have a tiny 2x2 grow tent that can't be fixed with a tiny dehumidifier inside to keep RH 40-45% during flower. So I bought a big nice quality dehumidifier and have it set to...

    New Buds look brown and dry. Am I in trouble?

    I am currently in my second week of flower, and all bud sites look "brownish" and dry. They don't look rotten or moldy, just brown..kind of lifeless. Could this be nutrient burn? Light/heat stress? Genetics? And most importantly, can I complete the harvest and hope that the buds eventually will...
