Hydroponic Weed Systems

“Grow your own weed, man”

Love it or hate it, perception of marijuana is starting to shift. Once thought of a gateway drug, or something only hippies smoked, today weed is rapidly being embraced…or, at least, tolerated. The medical community is starting to accept cannabis as a viable, natural alternative to chemical pharmaceuticals. And voters across the country are changing laws to allow for the consumption and cultivation of recreational marijuana.

So – if weed is suddenly legal to grow in your region – you may be wondering how to cultivate your own cannabis plants. The first step is choosing a hydroponic weed system that fits your needs. If you are not a hydroponics expert, fear not! We will review the 9 best hydroponic weed systems to make the decision-making process less stressful.

Why grow hydroponic weed?

People have been growing cannabis for over 12,000 years, making it one of the oldest agricultural crops. It produces more food, medicine, and fuel than any other plant. Hemp fiber is commonly used in the production of canvas, rope, paper and other materials. There are over 100 unique compounds in cannabis flowers and leaves, which tend to create interesting psychological and physical effects. So, there are a lot of reason why people choose to grow this versatile plant.

For home growers, hydroponics offers a superior growing method.  By using water and nutrients instead of soil, the nutrient solution goes directly to the plant’s roots. You adjust the elements within the growing environment to create these ideal growing conditions.  Provided the right conditions, hydroponics allows weed to reach its full genetic potential.

Here are a few benefits of growing weed using hydroponics vs soil:

  • Once your hydroponic weed system is up and running, it is easy to maintain
  • No soil mean less insects and pests, less soil-borne disease, and no weeding (no pun intended)
  • Allows for year-round, indoor growing for continuous growth cycles
  • Growing weed hydroponically can result in bigger plants and nearly double growth rates
  • Greater control of growing environment – including water, oxygen, nutrients, growing medium, light and temperature – can create the perfect growing conditions
  • Hydroponic growing mean space-saving efficiency and less water and nutrients wasted
  • Since you buy a hydroponic system (or create your own) and control the elements within the system, growing weed has never been more creative or engaging

Types of hydroponic weed systems

The purpose of a hydropic system is to deliver a water-based, nutrient-rich solution to plants. When it comes to growing cannabis, many weed cultivators favor methods such as the Ebb and Flow (also called the Flood and Drain), Deep Water Culture (DWC), or a top feed system, like the Drip System. Others prefer to grow weed using the Nutrient Film Technique (NFT), or mist the foliage of cannabis using the Aeroponic method. With that said, there are really no wrong systems to use when growing marijuana. To learn more about each technique, see our hydroponics systems page.

Things to Consider When Purchasing a Hydroponic Weed System

With all the options out there, choosing a system can be intimidating. Creating a hydroponic system from scratch can involve purchasing a reservoir, grow beds, growing medium, pots, nutrients and pH adjusters, and possibly more. The hassle and extra costs associated with buying each component separately – then piecing it together – can be daunting.

If you would rather buy everything separately, you are free to do so. But we recommend beginners and experts alike will find buying an all-in-one system much easier and more cost effective. Let’s look at nine of the best all-in-one hydroponic weed systems.
