    LED Sound Levels! Need Help!

    Hey RIU, I've been looking through here, and have been increasingly interested in LEDs. Mostly due to the claim of less heat output than HID/CFLs. I'm in need of help looking for an LED that has an actual draw of around 100-160~ watts. Most likely 180w-240w LEDs. I've done quite a bit of...

    Chop CHOP CHOP

    Hey RIU, Just thought I'd do kind of a "final post" thing lol. My last plants herm'd on me and it kinda came with an epiphany. I've been so sucked into this growing thing that I've realized that I almost neglected a lot of things... Not really neglected, but if I wasn't working my 10-12 hr...

    Stealth drying? Any advice?

    Hey RIU, I'm actually about three-four weeks away from harvest, but I want to try to get a head start on this drying process as it will be my first time.

    Problems with the plant! In need of urgent help! (Pics)

    Hey RIU. My Nirvana NL auto is about a month and half old, and it's been flowering I think for the past two and a half weeks or so?

    What kinda bug is this? (Pics inside)

    Hey RIU. I've recently having a bit of a pest problem I think. I have bitten leaves, but past few days, I haven't seen anything. (Sprayed 1/2 str azamax two days ago). Just now I found this small thing crawling on the OUTSIDE of my box. Might be what's eating at my plants? Any help would be great.

    Azamax... the climax. What now?

    Hello RIU! I desperately need some insight on anyone using azamax, or anything similar to it such as neem, bug off, etc. Three days ago, I sprayed my NL auto with azamax, b/c I finally found some evidence of some random little bug (I'm going with thrips) eating my crop. I took a 1/4 tsp of it...

    Hey RIU Recently I think I've just killed my five day old seedling from heat, and I'm considering just dropping a new bean. But my question is, can I take out the dead seedling and drop a new bean in the same old cup? Nothings been done to it except watering it twice. Thanks in advance!

    Hello RIU It's about that time when my grinder needs to be cleaned, and I wanted to make qwiso with it. The only problem is, from what I've heard, it's a pretty strong smell of alcohol, and I don't have the option to let it air dry in the open. So I thought about putting it in the box where the...
