co2 gear advice please

[copobo]

I guess I'll need a controller and regulator?

Anyone have any advice, models / vendors?

thanks in advance.

depends on your grow op. also you can wait out on buying a controller. digital timers work great, compared to mechanical tab timers. all you really need is a regulator, tank, hoses, and timer. hydrofarm makes a good starter kit with all that stuff except for the tank.
