Ok. So not much progress but a little.

I just finished building my carbon filter. It tool me about 45 min and I used the following items.

1 stocking
2 pots one slightly smaller than the other (I drilled lots more holes in the sides).
1kg of Active Carbon

I tested it and it restricts my airflow by about 30% (I am not sure how much a factory made one does).Once I get the other fan I will have to decide if I pipe them both to the same filter or if I build another one. Thoughts welcome

I think if I built another filter I would make a few small changes but it seems to work.

One quick question. Can I pull the air through a filter or should it be pushed?

Every setup I have seen has it being pushed through the filter.

you can pull or push .. the only place i really reccomend not pulling is on air cooled hoods because imho pulling hot air thru a fan cant be all that good for the bearings.
other than that pull / push whatever works for ya

Most common practice is to push it through but I haven't ever seen a good reason as to why. Light hoods should be pulled through however because if it is pushed through any leaks in the hood will pump hot air into the room.

I use 6" pots to start and go to 10" pots after the second set of clones is taken.

Ok. Not as much progress as I wanted this weekend. It’s been raining and I have not had a chance to get outside to cut the doors to size on the flower room. I'm leaving town for a few days for work so will try and finish it all on Thursday.

I have painted the flower box and put in the Mylar.

Ok so I have made some progress and altered my setup a little. I added another 100w CFL to my Veg box and got a smaller hood for my 130w CFL. I finally added a 6" exhaust fan and the temp seems to be running at about 78f. Which is a little higher than I want it to be for this time of year.

I also hung the doors to my flower box. I just need to finish the painting and then I can add my lighting and exhaust ducting.

Just some good bag seed at the moment and some clones so I can sex. I just got some G13 Northern Lights x Skunk that I will put in soon.

Me too. I just need to add the Mylar now and it's done. Then I can focus all my attention on finishing the flower box.

Thanks. Still a bit more work to do but its well on its way now. I will never build the cabinets again though. Next time I will just buy some. It took me way too long. I just want it finished so I can focus on the grow.
