This is my first grow. First off, the set up. I don't have pictures of the box.
The growing box is constructed from cardboard and lined with mylar. The box is 19 inches wide, 22 inches deep and 32 inches tall. Near the bottom I have a 120mm air intake fan and near the top I have a 120mm air...
120 mm is good.. Here's one for cheaper plus free shipping... http://dealextreme.com/details.dx/sku.5126

60 mm - http://dealextreme.com/details.dx/sku.5198
70 mm - http://dealextreme.com/details.dx/sku.5185
80 mm - http://dealextreme.com/details.dx/sku.9389
In my opinion, any 2 of these...
Here in Ontario I pay $20/eighth for mids ($40/qO, $80/halfO) and $40/eighth / $80/quarter for BC bud, strains including Timewarp, Pine berry, and Jack Herer.
