Possible growing space?

Ok, thanks for the heads up.
In order to fix that smelly problem I can either seal the cupboard, or drop the whole project.
Say I seal of the cupboard. Is it even with my fan blowing, 100% necessary to ventilate?

You see, my only option for ventilation is through those holes you see where the wires are. Then up and out the windows (curtains are in the picture). This would require a ventilation pipe or something, which would not be very discrete. Not to mention that the smell isn't gone, just brought out underneath the terasse where my mother spends half her day..

So I would be really happy to hear that I can make buds without ventilating a sealed enviorment, but if the facts say otherwise, then please inform me, because Norway isn't the best country to get caught doing this in.



I'm also going for a slightly smaller bucket, since this is my first grow and it's a tight space.
Not sure whats the best position of the fan.

Just wanted to update you on my indoor growing. It has gone pretty well in my opinion.

Strain: Northern Lights Automatic
2 x 40W 2700K CFL's
Emergency blanket reflective walls
Lies between 50% to 60% relative humidity at about 21-23 degrees celcius
11 L pot
Recieved vegetative fertilizer in the appropriate growth stage. Got general purpose fertilizer at the beginning of flower. And I quit fertilizing completely after I had to remove the top layer of the soil because of mold.

Mistakes so far:
Air vent got very slow when I applied activated carbon-filter. Too much resistance for the airflow. Resulted in high humidity. But the smell have so far been low enough to be handeled with incense.
A couple of days ago, I got mold in my soil. The reason must have been because I watered too often, but maybe because I let my window stand open a couple of hours to vent the room.
I let the plant grow all to high hahaha, I did top it, and I'm SO glad I did, but it was just in time, because I have now for a couple of weeks, tied the plant up in string. Which led to me braking off the biggest fan leaf on the plant. But it seems to thrive anyway.

Based on you guys' experience; How many grams of marihuana will I get from the top bud in the first picture when it is fully grown? It has 20-30 days to grow untill harvest (in my calculations).
Also based on your experience. Is this a good grow? Does it seem healthy? Is the size of the buds fairly good based on having a little under a month left?
