how to start weed seeds for hydroponics

Growing Seedlings with an Ebb & Flow System

It’s a pretty simple process really. The most challenging part can be figuring out how to support the developing plants bulk and weight depending on what kind of plants you choose to grow.

GERMINATE SEEDS:

Start your seeds separately in starter plugs in a tray under fluorescent light.
This allows for you to finish up the last group of plants that are still in the ebb & flow system for non-stop production.

TRANSPLANT TO EBB & FLOW HYDROPONICS SYSTEM:

When the system is prepared and ready, transfer the germinated seeds into it.
The starter plugs would be buried into your growing medium where the highest level of the flood process will just touch the bottom of the rooting plug. Leave room at the top of the pot to add growing medium later.

The flood will fill the containers to about 60% full, and depending on the growing medium that you choose, you’d flood an average of 2 to 4 times a day for 15 minutes each time.

As the plant grows, you can fill in the rest of the growing medium around the plant stem to help support the plant. If you add growing medium to the pots for added support, you should leave the flood height at the same level. Exposing a dry stem to an increased flood height may cause rot or mold to develop at the base of the stem.

MAINTAIN A CLEAN SYSTEM:

Your hydroponics system must be kept clean for the plants to stay healthy.

For maintenance, you’ll need to change the water in the reservoir every 2 weeks, replacing it with fresh water and nutrient.

Then, the PH needs to be maintained, which will require testing every few days and adjusting with PH up or down as necessary. (Same as a swimming pool or aquarium.)

PROTECT YOUR PLANTS FROM GARDEN PESTS:

Personally, I’d recommend integrating a preventative maintenance program of spraying for insects in order to avoid ever getting them.

You can use very natural and gentle sprays like Neem Oil , and apply once a week and you’d never run into any issues with insects at all.

Hydroponics – The complete guide from MSNL.

So you’ve decided you want to grow some fine cannabis but you might be a little confused with all the details of choosing and setting up a hydroponics system? Or perhaps you’re a seasoned grower but need a refresher or a quick reference? Here we cover the basics of what hydroponic systems are, how they are used for cultivating marijuana and the different kinds available.

The Basics

So what are hydroponics all about? It’s common knowledge that plants naturally grow in some type of soil or solid grow medium in order for roots to establish, which will then provide nutrients from the ground to feed the plant and allow it to flourish. Hydroponic gardening simply removes the soil and replaces it with an inert, soilless medium such as rockwool, clay pebbles or coco coir. Once established, the roots are then fed with a nutrient solution, the possibilities of which are numerous, more on that later.

So what is the purpose of ditching traditional soil and replacing it with a hydro kit? Traditional soil does have certain advantages over hydroponics but the main reason why so many growers go hydro is simple: bigger yields in a shorter amount of time. Traditional growing methods are dependent on the environment they are grown in, so they are susceptible to the sun (or lack thereof), precipitation (or lack thereof) and potential pests. With a hydroponic system, the grower is in complete control of all three elements. With ideal conditions (the right amount of light and nutrients), plants grow at an explosive rate (30-50% faster) and are ready for harvest much sooner than when grown in soil.

The History of Hydroponics

Hydroponic gardens can be dated back to the Hanging Gardens of Babylon as well as the Floating Gardens of China. This method has evidently been around for quite some time, however the credit for modern hydroponics goes to a man named William Frederick Gericke.

In 1929, while working for the University of California at Berkeley, he publicly promoted the notion of using solution culture for producing agricultural crops. The general public, along with Gericke’s colleagues doubted the idea, so to prove them wrong he grew 25-foot tomato vines using nothing but water and nutrients. He initially wanted to call the method aquaculture but later realized the term already existed and referred to the culture of aquatic organisms, so he went with the Greek terms of ‘hydro’ (water) and ‘ponos’ (labor) to get hydroponics. The method didn’t take off until after World War II when it expanded to countries in Europe, the Middle East and the Soviet Union

The prohibition of cannabis in the United States also made the conditions ripe for applying it to growing marijuana domestically vs. having it imported from countries like Mexico. Growing moved indoors out of sight of pesky law enforcement and could be done at a much faster rate with massive yields while using relatively little water and nutrients.
