sounds like you accidently fimmed.

nope. co2 is heavier than other air components and will tend to pool on the floor. just because the fan is pulling in air doesn't mean it's pulling more co2 than the other gasses in air. and carbon filters catch aromatic organic compounds that are chemically attracted to activated carbon...

everything still looks good. nube green thumb award

you can flower anytime you want. the longer you veg the bigger the plant and the higher the yield. but - you're out of space and they grow a lot in 12/12 so i'd start right away/

actually both/ - exhaust fan at the top and input fan on opposite side at the bottom.

welcome to riu. check out the links in my signature below for some growing tips from this site.

they never seem to grow fast at the very beginning. you should try for temps in the mid seventies.

ok, technically how he did it works, but it is not the optimal set up. by putting the filter on the outside and pushing air through it you are leaving all of the internal air smelling. any leaks in the box will smell like crazy. all commercial carbon filters are built to pull air through them.

nope. hps bulbs have a special socket and require a ballast to work.

impossible to give an answer without knowing more about your closet. it could be as simple as sticking the fan in an existing vent opening to as complicated as cutting through the ceiling and routing ducting around obstacles. is there an existing vent in the closet anywhere (floor, wall or...

just in case you change your mind, don't. a carbon filter does absolutely no good outside your grow space.

more important to have exhaust fans than intake fans. switch them around and just use a hole for intake. have the exhausts at the top of the box and the intake opposite at the bottom. temps should end up within 5 degrees of your ambient temp

depends on how much you want to yield. the 150 watt light has about 16,000 lumens and the 250 has about 28,000 lumens. you want about 14,000 lumens per average-sized plant.

no problems other than a little slower growth

just can't make a good call by those pics, and different strains can look very different, but i think seed pod

you sure those aren't seed pods instead of pollen sacks?

not change at all. but you need to make sure you buy cords that are rated for the amperage of your lights, plus a safety factor.

you are eventually going to need more light. an adult plant needs about 75 actual watts of fluorescent light to make a good amount of weed. also, only female plants produce usable amounts so you're better off planting more than one seed to increase your chances of having a female. you don't...

sorry, not much of a hydro person so don't know all the signs in your environment.

the seed pods are extensions of the bud and the pollen sacks are at the juncture of the node. squeeze a pollen sack and you get powder, squeeze a seed pod and you get either a seed or nothing.
