Thanks for the tips. Sage advice like this is what makes this community great.

Looking good! Regarding the temp, 22.1C struck me as a bit chilly, but at 40% RH I see that's a spot on VPD of 1.3.

Yep - Live and learn. :)

Amazing how much these plants can grow in 12 days! 8/7 8/19

Awesome! That's the kind of shit I love. Some call it overkill, but I say if it's cool as hell and doesn't hurt, go for it!

Oh shit. Now that's tempting! But my rational side thinks I probably shouldn't sink so much money into a single plant, hobby grow. :)

Has anyone studied the benefits of slowly turning the lights on and off? I know I'd be pissed if someone woke me up from a dead sleep by shining a spotlight in my face. Curious if our girls feel the same. It seems like a transition that mimics the rising and setting of the sun would be more...

She's restless at night! Time lapse with a shot each hour from 8am to 8pm...

Yep, my thoughts exactly. I'm thinking I'll go with the RSpec rather than the 3000K spectrum since my goal is quality over quantity.

She got some light defoliation this morning to expose a few bud sites. Also noticed the distinct odor of cannabis at the front door this morning. It's apparently time to rig up the O3 maker I got a while ago.

I've been using RH as the lever to keep VPD within range with temp constant at 78. Didn't realize CO2 was a factor. Though, I'm not supplementing with CO2 on purpose. My house just has higher than average levels.

Just switched to flower on my first grow. I've been targeting 78 degrees, but I've come across some folks aiming for the mid 80s. CO2 in my tent averages about 800ppm, so I could probably go higher than 78. But not sure what the benefit would be. Curious to hear what works for others.

Holy $hit man. You lighting up a stadium? That's a lot of firepower. :cool:

Thanks for the info! The HLG 135 rspec is just what I'm looking for.

Hey guys and gals, I want to upgrade the lights in my 2x2 tent for my next (2nd) grow. I currently have a 170w Chinese light w/ 2 COBs + 24 LEDs. I can't decide whether to go the easy route with the HGL 100 V2 kit, or spend a little more cash and effort on a QB96 Elite V2 DIY setup. Im...

Picked up some new hardware for my next grow. My root zone temp control is going to be awesome. Anyone grow weed in an igloo cooler before? :)

Appreciate your input! Now I've got a bug to build my own. :)

No worries. Looking good man! Makes me want a larger grow space... I'm officially out of room :)

Can you elaborate? My plant seems to like it so far, but this is my first grow so what do I know. I guess I won't know for sure until harvest. What would you recommend for a single plant in a 2x2 tent?

Awesome! Thanks man! I'm coming up with ~ 0.0145 for the cobs (1/69 from that thread) and ~ 0.0887 for the 5w LEDs (reverse engineering the calculator at the other link) I think I'll just measure the lux of each separately rather than take an average.
