starting marijuana seeds hydroponically

m) pH and PPM meters

Aeroponics is perhaps the most futuristic version of hydroponic growing, and uses misted water dispersed through the air to optimise aeration and hydration. Plants are placed into the top of a large tank of water filling the bottom 25%. Under the water is a pump that sends water into misters underneath the root systems. This fine mist constantly soaks the roots, allowing plants to receive massive quantities of air and water simultaneously.


An ebb and flow (also known as flood and drain) system features water that, well, ebbs and flows. These systems consist of several buckets suspended above a growing tray that features a water inlet and outlet. Both of these waterways are connected to an external tank that contains nutrients, an air stone to aerate the water supply, and a pump to move water into the growing tray. The roots in these systems are not continuously submerged within water. Instead, water periodically floods the growing tray with fresh oxygen and nutrient-enriched water. Once the pump cycle ends, all of the water drains back into the external tank.

Moving closer in time to the 10th and 11th centuries, the Aztec civilisation was also known to utilise hydroponics to provide sustenance to their society. After being forced from their land via conflict, these people settled at Lake Tenochtitlan. They proceeded to build floating rafts topped with soil, allowing crops to grow through the tap layer and spread their roots into the waters below.

As one of the most popular options, clay pebbles are excellent at aerating root systems. Clay pebbles sometimes require that growers alter the pH in order to provide an optimal growing environment, however, pre-altered pebbles can be purchased. You’ll need to place clay pebbles into a plastic hydroponic basket that has spaces for roots to grow through.

These seedlings were sprouted using the paper towel method!

2.) Germination for Hydroponics

I’ve tried a bunch of different germination methods over the years, and the technique I prefer is for hydroponics is starting with the “Paper towel method” to germinate, putting the germinated seeds into Rapid Rooters, and installing the Rapid Rooters directly into reservoir. Lots of other germination methods as well, but this has worked best for me!

4.) Prepare Hydro System for Its New Guest

Gently place the germinated seed inside, root down
