Hey guys, a question about ducting and fans...

We will be using ducting in our next cycle and we have some questions. First, how many inline fans do you need to properly vent your entire duct system? Some setups I see use one fan... we will be using four lights next time. Also, is it necessary to use hard pipe in your duct system or can you use all flex as long as you set it up with no restrictions and no bends? Intake-->light-->light-->light-->light-->exhaust through opposite wall?

Also, what is your opinion on using MH bulbs the last week or two before harvest?

Thanks for reading.

An 8" valuline fan and and a y adapter should be sufficient. A duct booster helps for your intake. You don't need to use hard ducting unless your dealing with flames. You would be fine using flex.
