600W HPS Grow Setup (For Hobbyist Growers)

 

About This Setup

The 600W HPS is one of the most powerful and efficient setups you can buy to grow your own cannabis at home. Although the technology behind it is archaic, there’s no denying the high-yielding, high-potency power of the might 600W HPS. Part of the true power of this light comes from the fact that it can be kept so close to plants (as close as 8-10″) while lights of similar wattage have to be kept much further away (18″+).

Pros: Crazy yields, super high potency, most electrically efficient HPS, relatively cheap to buy

Cons: Old technology, emits suspicious yellow light, poorly-made models emit RFI, can get pretty hot
