Will this get the job done?

I was wondering would 4- 600watt hps be good enough to get great quality bud out of a 9'x9' room of 2' plants in 5 gallon buckets (soil grow)..??

For flowering, IMO, yes, plenty. I'll assume you've a plan for the heat. Good luck.

well MH for veg would help alot maybe get digital switchable ballast or 2 of each haveing MH in with HPS for flower is spose to be good for your plants, the added spetrum helps promote thc production i think

i have a 400watt MH for veg along with 4-4ft floro fixtures for side lighting.. and yes i have planned for the heat issue.. i will be using a Vortex Powerfan.. it's 8" and is rated at 749cfm... i will have this fan on a dimmer switch so that i can control the speed if needed..

5 gallon pots for 2' plants? I wouldn't go with anything bigger than 3 gallon, unless you're are topping and pruning to keep them at 2 ft (longer veg time - more time for roots to grow) but if your just going to flower after they reach 2 ft, you have 2 -3 gallons of wasted space in your containers. Do three gallon pots and then you'll be able to utilize your grow room space and have more plants. I use 2 gal. pots for 2' ft plants which work very well. The general rule is have 1 gallon of container space for every foot of growth.

the plants will be pruned and tied down.. so the 5 gallon bucket will be full with roots.. Also the place that i work at throws out the buckets.. so i basically bring them home.. so they are free for me..

anyone have any questions or comments for me?
