Some One HELP PLEASE

:(please some one lol any one

lol I guess no one wants to help this lost canadian

When your can fan comes in, mount it as the exhaust HIGH in the room. Exhaust high, intake low. Take advantage of natural thermal currents. You can use that 4" for an active intake right where it is, just turn it around.

o thanx a lot now from the top of my rez to the light is just over 30" is that enough for lowrider and also how many poted plants do you think i could fit in there?

Personally I wouldn't put any potted plants in there... I could just see pests from them getting into your grow :(

no i meant like strile soile for some more lowrides and just water them with nutes space wise i think i could fit another 4 - 6 but im a n00b so i dont kno shit:P

also my lowrider-master low seeds have cracked so i put them into jiffy pellits and they have bin in there for about 4 days not all of the seeds have cracked 16 seeds 6 have cracked so far any idea how long it will take for the sprouts to shoot up or the other seeds will crack?
