The best cannabis seeds for hydroponics growing

However, it’s only recently that more cannabis growers are switching from soil to hydroponics setups. While these soilless methods aren’t super forgiving, they have the potential to produce bigger yields in a shorter time.

Since hydroponics requires a steeper learning curve, new cultivators must carefully consider which strain to grow before experimenting with this growing method. Starting with the right hybrid could save you a lot of headaches as you’re growing your herbs hydroponically.

What are the best cannabis seeds for hydroponics?

Since hydroponics systems aren’t as forgiving as soil, it’s best to start with strains that have solid genetics. While there’s no particular hybrid that’s perfect for hydroponics, beginner-friendly cultivars tend to work well in these units.

In general, when shopping for hydroponics cannabis seeds, look for strains that have a relatively low difficulty. This simple strategy should increase your odds of success.

Northern Lights

Here’s a more in-depth look at the best cannabis seeds for hydroponics and what makes them unique.

Northern Lights

  • Autoflower: No
  • Often categorized as indica
  • Feminized
  • THC: 22%
  • CBG: 1%
  • Height: 3.5 – 5 feet
  • Time: 8 – 9 weeks
  • Caryophyllene, humulene , limonene, terpinolene

Northern Lights is every insomniac’s favorite indica. Not only is this earthy strain celebrated amongst medical cannabis patients, it’s an excellent choice for new cultivators.

Since Northern Lights is considered a full indica variety, it’s quite sturdy and doesn’t grow super tall. Within about 8 – 9 weeks, you should be ready to harvest these dense nugs from your hydroponic unit.

Blue Dream

  • Autoflower: No
  • Often categorized as hybrid
  • Feminized
  • THC: 19.2%
  • CBD: 0.1%
  • Height: 6.5 – 8 feet
  • Time: 8 – 9 weeks

The only downside of growing Blue Dream indoors is that it can get pretty tall. Ideally, you should know training techniques like LST to keep Blue Dream’s buds in check.

White Widow Autoflower

  • Autoflower: Yes
  • Often categorized as hybrid
  • Feminized
  • THC: 19%
  • CBD: ≤ 1%
  • Height: ~ 2 feet
  • Time: 8 – 9 weeks
  • Terpenes: Limonene, terpinolene, and beta-pinene

The original White Widow cultivar isn’t too tricky to grow, but using the autoflowering variety in a hydroponics unit is even easier. Since these strains flower without a change in light schedule, they don’t require as much skill as regular cannabis strains.

If you’re new to hydroponics, it’s best to go with well-reviewed auto strains like White Widow. Sure, the final result may not be as intense as the original, but this White Widow has plenty of pungency and head buzz effects. Plus, there’s a greater chance Auto White Widow will absorb a few minor mistakes.

Gorilla Glue #4

  • Autoflower: No
  • Often categorized as hybrid
  • Feminized
  • THC: 21.3%
  • CBG: 0.5%
  • Height: 5 – 6 feet
  • Time: 9 weeks
  • Terpenes: Beta-caryophyllene, limonene, and myrcene

Gorilla Glue #4 is one of a few award-winning strains that seem to perform better in hydroponics units. Arguably, this mainly has to do with GG4’s higher-than-average watering requirements.

Since hydroponics plants have direct access to water, there’s less risk of under or overwatering this flower. This easier access to water may also reduce GG4’s heightened risk for hermaphroditism.

Anyone who loves sedative indica hybrids with diesel and chocolate aromatics should add GG4 to their hydroponics plan.

What is growing marijuana in hydroponics?

The term hydroponic refers to cultivating plants without soil and literally means “water-working” coming from the Greek words “hydro” meaning water and “ponos” meaning labor. 3

There are many different hydroponics setups on the market, but none rely on soil as a grow medium. Instead, these systems use water, air bubbles, and store-bought nutrients to supply the cannabis plant’s roots with everything they need.

Some hydroponics systems also use pH-corrected inert mediums to stabilize roots. A few of the most commonly used inert products include clay pebbles, coco coir, and Rockwool. 4

Since the roots in hydroponics systems are exposed, they can absorb nutrients faster. On the positive side, this means plants will grow more quickly as they don’t have soil as a buffer. However, this lack of “buffer space” means there’s less room for error. 5

Here’s an overview of the most popular hydroponics systems for cannabis:

  • Deep water culture: plant roots touch stagnant water in a bucket with an airstone for oxygen.
  • Ebb and flow: water and nutrients from a reservoir push through containers with cannabis at pre-set intervals.
  • Drip irrigation: nutrient-rich water “drips” into cannabis plants’ roots, which are suspended in containers with inert materials.
  • Aeroponics: cannabis strains sit in chambers where they get sprayed with nutrient-rich mist at regular intervals.

How do you grow cannabis hydroponically?

Growing cannabis hydroponically is similar to using soil, but it requires more diligence on the part of the grower.

No matter which hydroponic system you use, it won’t hide mistakes as well as soil. Hydroponics growers have to be extra careful about factors like pH level, temperature, and nutrient feeding to ensure their girls grow nice and healthy. 6

Generally, hydroponics growers need to maintain a slightly acidic pH in the water at around 5.5 – 5.8. It’s also imperative for ambient temperature to remain between 73° F – 83° F and water temp to be at ~ 68° F. 7

Speaking of water, you’ll need to monitor the water for signs of algae. This is especially true if you’re using Deep Water Culture, since water in this system doesn’t constantly circulate. 8

When using hydroponics, it’s important to invest in macro and micronutrients for your flowers. Since plants can’t absorb as many nutrients from plain water, you’re going to have to add more to your reservoir at regular intervals.

Just be sure to avoid the temptation to overfeed your plants. Yes, hydroponics units need more nutrients, but it’s still better to underfeed rather than risk “nutrient burn.”

Do you need special cannabis seeds for hydroponics?

Some strains may perform better in hydroponics units, but there aren’t “special seeds” for hydroponics. You could grow any cannabis strain you like in any hydroponics setup.

The key determinant for success is your comfort in growing a chosen cannabis strain. If you have a lot of experience with a particular hybrid, chances are you’ll have an easier time adjusting to a new hydroponics system.

Should you grow cannabis with soil or hydroponics?

There are endless debates over the benefits and drawbacks of soil versus hydroponics. However, most cultivators agree that hydroponics has a higher learning curve. So, if you’re new to cultivating cannabis, it’s probably best to master your favorite strains in soil before dabbling with hydroponics.

While hydroponics usually rewards growers with faster and bigger yields, they require more attention to detail. Also, hydroponics are traditionally more expensive to maintain versus a DIY soil grow.

Of course, this doesn’t mean you can’t go straight into hydroponics if you want to take advantage of faster growing times. Just be sure to constantly monitor your grow room’s specs for a successful experience.

Is it worth the trouble to grow hydroponics cannabis seeds?

Hydroponics isn’t as simple as soil growing, but it’s the better option for indoor growers who want a greater ROI. Also, “control freak” cultivators often prefer adjusting variables like nutrients in hydroponics versus soil. If you’re interested in getting the biggest cannabis yields, it pays to learn more about hydroponics growing. While you could still get excellent yields with soil, hydroponics will always reward growers with the fastest and fattest flowers.

5 Cannabis Strains Perfect For Deep Water Culture Hydroponics

Deep water culture offers some serious benefits when compared to growing in soil. But not all strains react the same to this method. Try out these 5 cultivars for the best results!

Deep water culture (DWC) is a form of hydroponics that immerses roots in a water reservoir throughout the entire duration of the grow. Plants are suspended above the water in net pots filled with clay pebbles to keep them secure, and their roots grow down into the reservoir below where they uptake nutrients. The nutrient solution is aerated by a device called an air stone, which pumps air into the water and allows the roots to breathe.

DWC is favoured by many cultivators because it’s very low maintenance and can easily be automated using timers, meaning it can be left alone for extended periods without intervention. Plants can also grow extremely large considering a large reservoir is provided. Nutrients are delivered directly to the roots, allowing strains to grow up to several centimetres per day in some cases.

DWC also removes the need to abide by a watering routine. The roots are permanently submerged—free to uptake as much water as they require. Practically any cannabis strain can be used in a DWC grow. However, some varieties are much better suited to this cultivation setup than others. Despite all the benefits of DWC, the lack of soil means there’s nothing to buffer the nutrients, and thus pH fluctuations are more common. As such, strains that can withstand a little bit of “turbulence” are best suited for this method. Check out the 5 best strains to use for DWC below!


Amnesia Haze is a strain known around the world for her fun and energetic sativa high, great productivity, and tantalising tastes. This lady was first bred in the European cannabis capital of Amsterdam using Haze genetics from California. This award-winning variety has seen great success in the competition circuit, and was victorious at the High Times Cannabis Cup in 2004 and 2012. She produces a potent effect that borders on psychedelic—an electrifying high that takes hold of the neurons instantly and proceeds to elevate mood and provoke talkative and social behaviour. She’s an excellent daytime smoke when looking to zone into work. Her flowers produce high levels of THC and medium quantities of CBD.

Amnesia Haze is a superb option for DWC. She grows to a medium height and can be cultivated with ease in limited space. Expect an indoor yield of around 600g/m² after a flowering period of 12–13 weeks.


Gorilla Glue has a legendary status in the cannabis world. This variety is easily one of the more potent strains in existence, pumping out THC levels of between 24–26%, with some phenotypes even clocking in at 30%. Such power might seem like the result of a well planned breeding process, but the original Gorilla Glue was actually created by accident when a Chem Sis plant pollinated a Sour Dubb specimen. This well balanced hybrid produces a relaxing high that deeply stones the body, releases tension, extinguishes stress, and induces a meditative state. The terpene profile provides moreish notes of earth, sweetness, lemon, and pine.

Gorilla Glue is a great choice for DWC is you’re seeking potency. This lady will grow to a height of 90–150cm indoors and yield up to 560g/m² after a flowering time of 8–9 weeks.


Northern Lights is another titan strain that sits upon the pantheon of legendary genetics. This indica-dominant lady was created when genetics from a pure landrace strain were introduced to those of a Thai sativa. The result is an offspring loaded with alluring tastes, incredible potency, and therapeutic qualities. Northern Lights provides a soothing high that melts the muscles, diffuses tension, and makes the eyelids feel heavy. She’s an ideal smoke for the evening to help immerse yourself into the present moment and detach from the outside world for a while. This pleasant high is beneficial for stress, pain, and anxiety. Her buds ooze delicious flavour notes of fruit and sweetness.

Northern Lights is a productive strain that is highly compatible with DWC. Indoor plants grow to easily manageable heights of up to 120cm and are suitable for relatively small water reservoirs if space is an issue. Plants have a brief flowering time of 7 weeks and produce a rewarding yield of 500g/m².


Giant White Haze was born out of an ambitious breeding project involving legendary parent strains Haze and White Widow. This merging was a great success, and the progeny inherited the best traits of both parents. She’s equipped with an invigorating sativa high that sparks creative thoughts and helps the mind to hone in on a single task for long periods. Giant White Haze also offers therapeutic effects to medicinal users in terms of boosting appetite and decreasing anxiety. These effects are augmented by a terpene profile that generates tastes of earth and pine.

Giant White Haze is a highly productive strain that reaches a tall height. Plants grown using DWC will peak at a height of 200cm and yield around 600g/m² after 9–10 weeks of flowering.


If you’re a fan of body highs and nights spent satisfying the munchies, then try growing Critical via DWC. This indica-dominant strain has been the commercial grower’s go-to cash crop for years. Featuring characteristic hardiness in the grow room, she produces compact buds abundant with gooey, psychoactive resin. Prepare for a long-lasting and intense high that will leave you feeling rested and rejuvenated. If you want to take her strong effect to another level, make some cannabutter and cook up some brownies.

Critical is a great option for DWC growers seeking large hauls from vigorous plants. After just 7 weeks, indoor plants produce around 400g/m².
