Thanks a lot KK... Turns out hydro is not that difficult as long as you keep the PH within the limits. Unfortunately I didn't clone my baby, as I got absolutely no space to do so, and I have to move out in February, so I won't have anywhere to grow after that... So I won't be able to do a new grow before autumn 2010.
That is also why I'm not going to invest in a carbon scrubber right now. I however though about a plan that might work... I was thinking about taking a bucket, drill a small hole for an airhose. Then connect an airpump and fill the the bucket with cat litter. This should be able to capture some of the smell... What do you think?
