Chaz,
I have a couple questions about your tent set up. Please keep in mind im still learning in preperation for my first grow, so if some of what i say sounds dumb, attribute it to a newb learning lol.
In regards to the ventilation in your tent. I havent seen cooling ducts hooked up to a charcoal filter then into your light then out the tent. Ive always seen cooling for lights as a pass through type design meaning this...(Im going to try and explain this best i can, forgive me if i sound confusing)...You have your tent, light hung in the middle and then cooling ducts attached to each end of the light. Cool air is sucked from outside the tent, over the light, then exhausted outside the tent. I understand that using a charcoal filter is for odor elimination. However, i see two things that may or may not be a concern:
1. Pulling air from the tent to cool the light wouldnt be as effective as pulling air from outside of the tent unless the air outside the tent is substantially warmer than inside the tent (obviously).
2. Pulling air through the filter while also using that air to cool will cause some sort of reduced air flow and not allow for as cool a lamp as you could have, wouldnt it?
What im trying to say is wouldnt it be more effective and efficient to have two fans set up, one for cooling your light, and the other connected to the carbon filter that is vented outside for odor control?
