My plants were doing great, then yesterday I put this bag of Exhale Co2 stuff in the tent and now my plants look like they're dying! The temperature also got higher than normal, but I got it down to around 84 at the moment. Had to buy a humidifier at one point, might just get another one too. RH...

I've heard of a brand of nutrients called Canna. I have Happy Frog soil, and I know they have their own line of nutrients, but I would assume Canna is specifically designed for, well, Canna! Is there any reason to prefer one over the other? Does matching name brand nutes to their soil make any...

Would it make any kind of sense to use rockwool plugs and then plant them in soil? I know they're used in hydroponics, but do some ppl use them to germinate first? Seems like with the heat mat/humidity dome combo you can control it better, but do the plugs biodegrade over time or would it affect...

Shit, that makes perfect sense! Damn, why did I buy these things?...

I saw one yesterday, they are badass, but this little line of text in the catalog worries me: "Recommended for nine months of operation..." And the fixture only has a two year warranty? Are these things not designed for the long haul? Or do they mean the light should be replaced every nine...

Done and done. Buried the Jiffy Pots into one gallon pots with a nice breeze. Still don't know where they are in terms of water, but we'll see in the morning. Right now it's their bedtime.

Yeah, I was thinking about the round leaves. They're kind of dropping now, whereas earlier they were straight out. I did get a small clip fan, I'll throw that on them from a good distance.

How loud is the Hurricane? This Dura-Fan is freaking louuuuud!!! I guess regardless one of those damper things would be needed?

Holy fuck, I paid $130 for my fan! I'm buying the Hurricane and taking this one back! Thanks bro!

The one on the right...is that a sign of underwatering? Because earlier the jagged leaves on both were kind of pointing straight up, it looked kind of strange. The one on the left I think is about to shoot up another node, there's a little nub of growth in the middle of the leaf set. I just...

Well I went to the grow shop today and they educated me. Ended up with a 435 CFM Dura-Fan, much like that Hurricane you linked. I'll throw it up on the roof port with a connector port thing to attach to one end of the predator. He said to open the vents on the bottom of the tent and that I...

I'm thinking the fan I have now could be run straight into a bottom port as my intake air, 65 CFM. With the right equipment I could place the exhaust fan on the roof port, their 6' has 160 CFMs, which should be plenty strong even when I do get a filter, which isn't needed yet because I have all...

Keep in mind this box is tiny, 2x2x5. It has two little screens at the bottom with mylar Velcro things you can put over them. I thought that would help with air flow, but apparently not enough!

I took the bulb out when I wiped down the fixture, but I'm honestly a total noob when it comes to HIDs. It looked normal to me, the socket seems perfectly normal. I fired it up again and the smell was there coming out the back but not nearly as bad. However, I absolutely must find a way to vent...

Yeah, it's definitely coming from the fixture. Still smells a bit even though I had wiped it off some more. Oh well...

The Predator was actually a floor model that was hanging from the ceiling for years. It was dusty when I got it, but I thought I got it all. Probably not I'm guessing. I'm going to fire it up again and try to localize the smell. It should come out the bottom if it's from that.

I have a green Utilitech extension cord, supposed to be for outdoor stuff, an APC battery-backup outlet, weighs a ton, and had airflow all the way through the loop. My tent is only 20 cubic feet, and the fan was meant for it at first, then I had this idea. I still need a good clip fan for that...

It was more of a dusty smell, no sign of smoke, so I guess I'm alright?

So I finally upgraded to a real HID light setup! Got the Predator fixture, Hortilux Blue 400W and ballast, and a small 65 CFM fan to make a closed loop vent for the light. I still need a small clip fan for the inside, but at least the tent has some vent holes on the bottom sides. Anyways, I had...

Yeah, will prob do T5 after all. I would prob need a bigger darkroom to handle the Hortilux, 20 cu. ft. might be too small for 400W. I guess this will be my mother plant setup one day, but for now I'll just take these babies all the way, if that's even going to be possible. Just seeds from dirt...
