Ventilation setup`s
# 1 Ventiliation Explained - Part 1 | BGHydro
# 2 Ventilation Part II -- Choosing An Inline Fan
# 3 Ventilation Part III -- Installing an Exhaust Fan
but the FAQ DO NOT discuss some item`s that I am having problems whit

they do not discuss where you get the ā??fresh airā? from ?
Inside or outside your home ?
(is their moor co2 in out side or inside air ?
Sins im growing in winter outside air temp are in the 20"s
Do I use outside air ?

If using a active Ventilation sys what do you think of placing one fan in (drill a hole at the top of grow room and use some duct from the ceiling to the floor ) so you get the fresh air to the bottom of you plant`s ! ! ?
and one fan that is sucking air out of your lights in a air cool hood ?
(so you have one side of your air cooled hood light whit a duct and one side whit no duct ?
1 have 1000W on a light rail but I do want to add 2x400W or 2x600W later on
I want to use the heat from the HID`s to heat; my home to help off set the power cost of the grow room
hope you understand this ! !
