tax time upgrades

So what would you choose
Aircooled lights, seperate from everything with a 50lb filter and8 inch fan as scrubber in room with co2 gen and photocell controller
Open lights, scrubber setup and ac with co2
Vert bulbs scrubber ac and co2

Currently running aircooled lights with filter attached venting(8 inch fan)out the room and one vert bare bulb a have a 4 inch canfan for intake, just looking what others would do too add co2 to their setup

Scrubber / ac / CO2. Vertical or not depends on plant size imo.

Running at night when cooler you can help your ac by venting hoods with filtered air from outside thru hoods and back outside. Seal the duct work and hoods.
