Harvest a Pound Every Three Weeks!

Hey guys so I'm setting up my flower room now (I already got 2 I just switched the light cycle on) and this morning I've been thinking about light venting and I was just wonder on how you vent 2 lights? Can you do it with just one 440 CFM fan? I'd be running a 1000mh hps bulb supported with a 600 hps.

@MouseE I would think if your hoods are at least 6" that a 440cfm can pull air thru 2 hoods. That is as long as the length isn't obscenely long. Can always try and upgrade fan if it doesn't work.

So from my understanding (imagine from left to right) I'll close the end of one reflector, place in light, set up ducking to connect to next hood, in the middle of ducking between hoods put in fan, then connect ducking to out tent blowing into next room.

Or do I put it at the begging of the first hood blowing all the way through both lights and ducking?

@MouseE forgive the crude drawing. But this is how my tent is setup. Pulling air from outside tent thru light hoods and back out.

From my understanding you want the fan on the end pulling the air out. That's how I run my two tents that way.

Rule of thumb 200cfm per 1000 watts of light. I have a 740 for just 2 600 wattsSomewhat overkill...lol

Nice that's what I thought I was doing minus the ducking on left end. Your drawing is perfect

And yea I'm putting in a 440 for a 600 and 1000 and 220 in the tent to outer room for humidity. Then see if I need any upgrades after that

One 440 will be enough. I run my fans on the input of the lights. Your fan will get pretty hot if it's sucking warm air from the lights. I heard that the heat can lead to premature bearing failure.

Actually the "Rule of thumb" is from an old English common law that states, you can't beat your wife with a stick any larger than your thumb. Later the English changed the law to, you can't let your wife beat your dick if it's any smaller than your thumb. That's why the British never never get hand-jobs, it's against the law.

Holy moly, i dun even...


One more silly occurrence that came up (I hope!)
Aren't 6" inline fans suppose to be able to slip into 6" reflectors? My reflector has a grove like it was made to slip on a fan but when I try to put the 2 together...nothing

Also are grow tents made to be able to hold lights and stuff? The frame wobbles a bit don't want any disasters.

Inline fans connect to the hose so it's the same size as the reflector, 6"...

The tent frame should support a couple of lights no problem.

Awww hell yea, i should have some pretty pictures and eye candy coming soonish

So I finally got shit set up although made some pretty NOOB mistakes. But gotta hand it to you on the 1000hps stink, those things are straight ridic. I wasn't so sure about all the hype, but after finally plugging one in.....holy......fucking.....shit!
The light output from that thing is insane! Makes my old school led look like a silly lantern!

Unfortunately I'm having some ballests not working problem so for now I'm gonna put a 400 mh, a led, and a 1000hps in a 5x10x6 space. Setting the screen up next.

I modified stinks original plan so I could get 2 flowering units inside mah tent since I love hazes and wanna get into growing some of these 12+ week strains.

Which leads me to my first noob mistake, I got a tent too short!

The room I resurrected for this is huge, the ceiling is over 25 ft in some places and it's about a 15x40 room, I wanted to abuse the height space but unfortunately I can't just flop over the grow tent roof like i was hoping.

Maybe it's time to build that pvc frame, attach some boards, slap on this mylar sheet that's been sitting in my basement forever, and do some hydro scrogging.

Or maybe learn vertical growing?

Or maybe not be a noob and let my plants get retardly big. This one in the pic had a 8"wide wall/ball of root growing behind the pump. I think I let it veg for like 1 and a half months.

It's been through hell tho, from the 5 day power outage here (20 hour long days of hand spraying sure do suck!) to the giant amount of roots to this last move...it and the green crack just refuse to die though!!! Over 12 different plants have all bit the dust in the buckets through their life!

Couldn't find a way to hook up inline fan closer inside the tent so on the wall it went, there's a lot of ducking but I'm hoping it will be okay since I got only 1 light it's supporting.

Cant wait to put in the new upcoming girls next week I hope, unfortunately during the power outage the cat knocked over the unit and scattered/played with my plants on the floor so I lost all my labels except 4! Lemon alien dawg, gsc, northern lights, bay dream, and a Durban poison are the newest additions.

How do you guys secure fans in tents? wire hangings?

Hello all, hoping some of the more experienced eyes can help, not sure if these nuggets are ready yet.
also im having a hell of a time getting a consistent environment temp, the 347CFM isnt removing the heat from my 2x600's and dealing with the outside air is too unpredictable, today my lights off temp dropped to 62. lights on its back up to 78. If i had to pick either having temps at max get to 86 and use ice bottles to keep water cool, allowing perfect humidity and night temps, or, make sure temps never get above 79, plus bring in outside co2, but have big swings between night and day temps, and low humidity during lights on, which should i choose? .....

How did you solve the issue of the sprayers shooting water over the edge of the top container and the lid not being watertight?

im no expert here, but i taped some plastic to the lid to catch the spray, jus make sure its not hanging down too far and blocking your actually spray heads. i also had to seal the holes in the handles, moisture collected and dripped out of them

I put marine/automotive weather stripping on the top of the bin

So plants end up not too happy when they get neglected for a week. Cause you end up in the hospital. Water isn't ph'd, vegging plants are overcome with new uncontrolled growth, some cuttings died from unbalanced water. Soooo much catch up, and new cuttings.

Hey guys one of my cycle timers (fortunately my cheapers auto 4min on 1min off) fell in a bucket of water for about a day. You think it will still work (is safe to plug in?)?

I'm sorry shifty it's crazy how plants grow so fast sometime. Seems like they take forever to start vegging then even longer to recover from FIMMs then all of a sudden they burst out of control. One of my plants vegged for like over a month and its ridiculously big, I hope it doesn't stretch!

Anyone experiment with LSTs? I was thinking of drilling holes in the bucket, then putting in small wooden stakes or chopsticks, then tying the plants to that.
