A look back has seen us cover hydroponics systems that are either simple or advanced. Let’s add a nice middle ground to the mix. Ebb and Flow systems are simple, reliable, and low cost but require a little more work and maintenance than a drip system does.
Ebb and flow systems (or flood drain systems) are simple setups that use a flood and drain system to keep the growing medium moist. Since the water pump does not run constantly, these systems are quieter and consume less power than nutrient film or direct water systems. The trade-off is that water use is less efficient than in other systems. Since the roots are not in constant contact with the solution, there is more water waste here than in other systems – which can, of course, be mitigated by recycling your water. A growing medium is also required, which means regular cleaning and inspection for fungus or disease is necessary – this becomes an intensive task since the roots of every plant in the system tend to interweave. Even so, the system is cost effective and perfect for short plants or leafy vegetables. Ebb and flow systems are also really easy to build.

Every consumer car, truck, or van comes with lights pre-installed. Without lights, night driving would be practically impossible and bad-weather traffic would be extremely dangerous. The stock lighting kit that comes with your car is often incomplete, arriving with just enough lights to meet government specifications. Yet lighting almost always takes a back seat to other things, your sound system for instance, when it comes time for upgrades. But why upgrade lights if they haven’t burned out yet? Well it’s more than just upgrading headlights. A car with a full light kit includes additional lights such as fog lamps, driver lights, and parking lights.

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.

The simplest way to show depth is by placing one object behind another object to show space between them. When you place light behind an object, you gain depth and a combination of beautiful shadows with a warm glow that highlights the object for stunning displays or haunting beauty. However, not every design uses – nor should use – the same lighting techniques and principles as every other. So let’s take a look at 4 places to use backlighting that aren’t Instagram pictures.

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.
