How to Set Up a Nutrient Film Technique (NFT) System

Sep 08, 14 How to Set Up a Nutrient Film Technique (NFT) System

Drip and DWC systems are good options for beginners, but advanced growers may want a more formalized system for growing crops regularly. For larger scale projects, let’s take a look at the Nutrient Film Technique.  NFT systems use a very shallow stream of water and dissolved nutrients flowing over the roots of your plants to feed and water them.  The partially exposed roots and constant moving water keeps them oxygenated as well .  This shallow stream is little more than a film of water flowing via gravity down to the bottom of the channel, which gives the technique its name.

Direct Water Culture (DWC) and You

Aug 25, 14 Direct Water Culture (DWC) and You

So you’ve taken a look at how to set up a drip irrigation system and decided that it’s not for you.  Well the good news is that there are plenty more hydroponics systems for you to experiment with.  So let’s talk about direct water culture (DWC) today.  DWC systems – also known as deep water culture systems – submerge the roots of your plants in a nutrient solution.  This sounds, at first, like a bad idea since you can overwater plants, but that’s where the all-important aeration component comes into play.  Aeration is simply the act of adding oxygen to the water to sustain the roots.  The way you aerate your system defines the type of DWC it is, whether you use a bucket reservoir, prefer bubbleponics, or enjoy a re-circulation system.

How to Set Up a Drip Irrigation System

Aug 11, 14 How to Set Up a Drip Irrigation System

Let’s talk about drip systems.  With so many hydro systems available, why should you pick a drip system over a nutrient film or ebb and flow system?  Simplicity is one reason.  A drip system is really simple to set up and has been used in outdoor gardens and larger irrigation systems for a long time while film and ebb and flow systems require more careful monitoring and can be tricky to set up properly.  The second reason is water conservation.  When you’re building a hydro system outside, the run-off water can be returned to the soil cycle instead of down the drain like with indoor setups.  A drip system also carefully releases just enough nutrient solution to keep your plants healthy, so there isn’t any wasted water.  Other hydro systems use a lot of constantly flowing water to prevent stagnation.  With a drip system, you can even give specific amounts of nutrients to different types of plants on the same line.  Let me show you how easy it really is to set up a drip system.

Jul 28, 14 How to Cool Down your Grow Room

The last time I covered hydroponics, I talked about general air circulation and how important it is to keep a breeze cycling through your grow room.  With the sizzling hot month of August looming ahead and the summer heat adding up, the dangers of excess heat from lighting and improper ventilation in your grow room can become extremely dangerous to your plants.  But can you actually do anything about the annual heat wave?  Take a look below for some helpful tips on how to stay frosty and keep your plants cool.

Air Circulation: What You Need to Know

Jul 14, 14 Air Circulation: What You Need to Know

Most of our world is a layered mass of solids and liquids.  Stacked on top is a thin layer of invisible gas we call air.  While mostly inert nitrogen, air contains the elements needed by almost every living thing and plants use both oxygen and CO2 depending on the day/night cycle.  Plants breathe using the stomata, or pores, underneath their leaves.  Over time these pores can get clogged by dirt, dust, or other air-borne particles pretty easily.  Usually, rain and wind wash and dry the leaves to keep them clean while moving fresh air around them, but in a greenhouse or grow room you have to replicate the effect using ventilation systems and sprays.
