The General Hydroponics GH4830 Drip Hydroponics System at a Glance

The GH4830 is as simple as it gets. But don’t take that to mean this drip hydroponics system can’t keep up with more complex (and more expensive) systems. If you’re looking for a well-built system that is able to grow larger plants without breaking the bank, the GH4830 is for you.


At under $100, the GH4830 is a cheap way to start growing large plants reliably. The system has many pros, including:

  • A massive reservoir. At 5.7 gallons in total size, the GH4830 has a reservoir that holds 2.5 gallons of nutrient solution and 3 gallons of the included expanded clay growing medium.
  • Included growing medium. While this isn’t advertised, the GH4830 includes a 9 liter bag of expanded clay hydroton rocks.
  • Included nutrients. The system also comes with 3-part flora series nutrients, meaning you can hop right into your first grow with everything included.
  • A UV-resistant reservoir gauge. Anyone who has ever had a system without a reservoir level indicator knows the pain of checking reservoir levels without one. In addition, the deep blue tube ensures UV light doesn’t enter the system, reducing the chance of algae. 
  • Expandable. Buying a system with the ability to add to it in the future is always a plus. The GH4830 allows expansion by adding more units. You can even add a General Hydroponics controller and external reservoir(s).
  • Sturdy construction. Cheap hydroponics systems sometimes feel just that: cheap. The GH4830 is definitely an exception. The build quality is top-notch and sturdy.

If you are looking to start out growing multiple large plants, you can find a cheaper system per plant than the GH4830. For instance, the Viagrow DWC system and General Hydroponics GH4720 both can grow 8 plants for a lower cost per plant.

Drip hydroponics, while reliable and simple, can’t keep up with a well-tuned aeroponic or NFT system. That said, you’ll still be growing way faster than soil and learning a ton while you do. In our opinion, it’s best to save the more advanced techniques for after you’ve mastered the basics.

Lastly, some users have reported difficulty in seeing the water level through the blue reservoir gauge. We personally didn’t find this to be a problem when we had our grow lights on. However, it is something to keep in mind if you check your reservoir levels when your grow lights are off. That said, we think it’s better for the tube to block UV and be a bit harder to gauge water levels than vice versa.


While the GH4830 drip hydroponics system comes with everything you need to start growing, you may want want to add on to the system as you go. The system doesn’t come with PH measurement or control capabilities. If your plants seem to be suffering issues related to PH, this is the first thing to add.

In addition, you can add a thermometor/hygrometer like the Acurite 0063 to make sure your plants are staying in their climate sweet spot.

While the GH4830 drip hydroponics system is great for large plants, it’s not the best system for starting smaller plants. A smaller system like this 12 Site Aeroponic Cloner can get your plants rooted faster for not much extra cost. In addition, one cloning system can support up to 12 GH4830s, so you’ll have plenty of room for expansion.


If you are looking for an easy way to start growing one or two large plants, the GH4830 is your best choice. However, if you’re looking to grow more plants, you’ll likely want to look at a bigger system. The GH4830 comes with everything you need to get started and setup is a breeze. In fact, it’s the easiest system we have used.
