8x10x8 ft marijuana grow room


A question from a fellow grower:

Recently I’ve been interested growing and was wondering what I would need to get the process up and running. For the flowering process, how many and what watt size HPS lamps would I need to get for a room 8x10x8 ft and also for the growing process, how many and what size watt MH lamps would I need to purchase?

If I use 6x 600watt HPS in my grow room what would be a good ventilation system?


Light density is your choice. 6-600watt will be all you would need.

Ventilation system is determined by how fast you want the aor exchange to take place. Fans are rate by cubic feet per minute. Divide this time duration of minutes into the cubic size of the room, and this will tell you what size fan/s to get. Or; Divide Fan size into Cubic size of space; This will tell you how long it will take for that fan size to exchange air in the room.

Hope this helps. :slight_smile:
