9 Best Hydroponic Systems for Growing Cannabis

best hydroponic system

If you are a new cannabis grower, you may be a little bit overwhelmed with all of the gear and know-how that you need for a successful indoor grow operation. You will need a lot of equipment to set up your own hydroponics system from scratch, including materials for starting seeds, grow tray, reservoir, hydroponic lights, pots, growing medium, nutrients, inline fans for ventilation and more. The hydroponics systems in this list take the guesswork out for you and allow you to start growing weed from scratch faster. I’ve organized the list by my personal preference, with my favorite system in the #1 spot.
