yes. my 6" inline fan is constantly on pulling air out of a 4x4x8 room and bringing fresh air in through a couple passive air intakes. there is also an oscillating fan inside blowing at the plants. if i turn off the inline fan it gets pretty warm (80+ degrees) and i'm still using fluoros. the...

i am a bit puzzled about how to do this. i understand air exchange is important for healthy plants. i run a 400cfm inline 24/7 at low-speed to do it. this has probably cost me a little more in electricity but i don't care if it gets the job done. i'm wondering if other people do the same with a...

I am also going to be cooling a 400w HPS in a cooltube. Will I be okay running the 6" inline fan at half speed with the speed controller? Is "medium" on the dial roughly 200cfm? Also, do a couple right angle bends in the 6" ducting reduce the CFM rating? Anyone else using a CAN33 with a...

I am a little confused about the ratings listed for carbon filters on websites. My CAN filter has something called a "Maximum Exhaust CFM" which is 200cfm, and something called a "Max Recirculating/Scrubbing CFM" which is 400cfm. I have a 6" Inline Fan hooked up to a speed controller that's...

well i lucked out and 5 of my 6 plants turned out to be ladies. 2 ak's and 3 white widows. problem is that is too many for my personal grow. i would be happy with just 2 nice females, one of each strain, keeping them as mothers and taking clones off them. my question is what sort of...

i was leaning towards male also but i was just curious. this is sorta what it looks like to me when i observed under a jeweler's loupe

I will wait a while just to be sure, but what do you guys think. Male or Female? Sorry for the quality of the pix

Ok guys i took some pics, basically I want to know if this is normal or if I screwed up somewhere... I'm going to hang this fan vertically so the exhaust is pushing air straight up. I'm going to run some strong wire through the holes in the mounting brackets to hang. The holes are too small...

Why do these fans have such useless mounting brackets? Anyone who owns one of these fans please tell me how you hung them safely. The mounting brackets fit very loose on my 6" fan and make me uncomfortable with using them to hang over my plants. It's like they give you screws that are too short...

tmi...........

by chance i just happened to be looking out my window and spotted a black SUV with two guys in it (not parked, but coming out of an alley). i'm not good at making out models but it looked like one of those big american cars, maybe a Ford. anyways the scary part is it drove a full circle around...

this is a small annoyance i have with soil grows. my pots have lots of holes at the bottom, so whenever the soil is relatively dry, a little falls out the bottom when i move them around. how do i prevent this from happening? i was thinking of putting some netting, the kind on screen doors used...

did you mean Zero Tolerance? that's the only Ed rosenthal product i could find. thanks for the tip i will try it if this doesn't work

ok got it.

thx they are gone

thx its looking better now

ok i will def transplant it to a bigger container next watering. i'm pretty sure i'm not overwatering though. i wait until the soil is bone dry. that's why i'm puzzled as to whats wrong, im thinking its N toxicity but i can't be sure.

this is a 3 week old white widow growing in 8oz cup of FF ocean forest, its extremely droopy and stunted, leaves are papery dry and "claw-like". i don't know whats wrong with it but i'm using t5s so temperature is fine (mid 70s), humidity is in the 35-40 range. i thought i gave it too many nutes...

this is a really dumb question folks but exactly how do you arrange a cooltube, inline fan, and carbon filter together in, say, a 4x6 closet? i know where to exhaust the hot air (through a hole in the ceiling of said closet) and where to pull in the fresh air (through a couple small holes in the...
