hmm.. i started with one plant as a mother in a cooker housing i got from work and it didnt really smell, then i put her outside on her regen in march and got some really nice bud, then some time later i had 6 plants in veg in a bedsit in the shower(i used the communal shower

), i used a re-curculating fan and the extractor fan that was in their originaly,
it only really smelled towards the end of flowering, which i came very close to getting caught when i came home from work one day and my landlord was going in next door to collect rent, i pretended i was looking for my keys (thinking oh no oh no) and he said to me "a few people have been complaining about a smell"(my heart sunk)
so i said "hmm thats strange i wonder where its coming from"(noticing a bright orange glow coming from a seam in the door!) then he suddenly said "hey i have another bedsit further down the road if you want to take a look",
and i replied "yeah that would be great"(shit shit shit

) so i went to look at it and told him ide move in their tomorrow, when i got back into my flat i had the whole setup down and all the buds in a bin liner in about 5 minuites

, omg that was the biggest buzz i ever had heart pounding the works!,
anyhoo so yeah i ended up moving into this other bedsit for the same amount of money and it was aweful the kitchen had been their since 1800's, infact i nearly got set on fire when the fuse board started flaming, ohhh what a nightmare that was,
so the moral here is "listen to the experts!"
i really appreciate all of you guys help and i will have to save for a while to get me a carbon filter and fan i will start germination and get vegging, and by the time their anywhere near flowering i hould have the money for a carbon filter

Edit: oh and in those days i didnt have tinternet

and that was when i bought my 400w and my 600 watt hps about 5 years ago an they still work well yey!
