Growing this strain in a hydroponic setup will let her fully develop, growing up to 150cm and producing huge yields.

The nutrient film technique consists of exposing the roots to the air permanently and keeping a thin flow of water along the bottom in which the tips of the roots are soaked, providing the nutrients they need while the rest of the roots are exposed to oxygen.

No matter which hydroponic system you choose you’ll need:

5. Most Common Mistakes When Growing Hydroponically

As we know, oxygen is essential for plants, so you need to use an air stone in this setup to keep the solution oxygenated.

There is an adaptation of the drip irrigation technique called Continuous drip irrigation. It uses the same setup but instead of watering when the timer turns on, the water pump never turns off, providing a continuous flow of solution for the plant. Like in the DWC technique, this way the plants can be fed whenever they need to and will result in faster growth and much bigger plants.

Now, there’s a lot of debate about which ones are better, LEDs or light bulbs but the truth is that you can get really good results with both, it’s just a matter of knowing how to use them but LEDs are usually preferred by growers due to their full-spectrum.

Hydro setups: Wick System

Before talking about the different hydroponic setups we must advise that in hydroponic grow is essential to measure pH and PPM levels every day. We use the pH meter to know how alkaline or acidic our solution is and the EC meter is used to measure PPM levels (PPM means particles per million).

By maintaining good growing conditions throughout the whole grow cycle you can expect huge yields of up to 600gr/m2 so it’s definitely a must for hydro growers.

*Note: Germination (7-10 day’s) low light levels, ideally T5 lighting. (20/4)

Short-day plants vegetate best when the daylight hours are extended beyond normal. When the day hours are longer, the P-fr (Far-red) stores, cannot fully decay before the light comes back on, keeping the plant in a vegetative state.

Auto flowering varieties completely mature from seed to harvest in 8-12 weeks, which means they are not subject to photoperiodism.


Short-day plants exposed to a longer dark period (12+ hours) are able to fully decay their built-up stores of p-fr, which initiates phytochrome to trigger flowering.


Over the entire grow most Auto’s will generally not consume an EC above 1.8, in fact an EC higher will create the exact opposite of the intended outcome.


Growing auto flowering varieties has become quite popular amongst the new generation of hobby growers due to their fast turnaround and compact size, making them ideal for many new and experienced growers.

Like any plant we are feeding, we don’t go straight to the max dose, rather a gradual build of nutrition, relative to the growth of the plant.
