Ventilation is extremely important to your plants. Without proper ventilation, CO2 levels can become stagnant around plants and temperatures can reach damaging levels. Regular air flow is necessary to refresh the air with a new supply of CO2 while keeping lamps and plants cool in hot weather. While we’ve covered methods of cooling, and the effects of air circulation in your grow room before, we haven’t really spoken on how to properly set up a ventilation system in your greenhouse. You’ll find there are two common types of ventilation: IN/OUT and Controlled Environment Agriculture (CEA).

We have posted many guides and FAQs for LED lights, but it’s difficult to cover everything in a single article. LEDs are more complicated than any previous lamp, and it can take a while to learn everything about them. Recently, I helped my Dad’s church move from the traditional incandescents their building had used for 100 years, to the LEDs in their new building. They had several questions, such as cost and lifespan, with more adding on even after everything was installed. So I’d like to pass these common questions, and their answers, on to you.

The decision has been made: You want to grow something with this great system you’ve heard about called hydroponics. Maybe you’ve already decided what type of system you like, or maybe you aren’t sure where to start. For either case, you’ll need to decide on what kind of growing medium you want to try. Hydroponics systems don’t use soil, which opens up an entirely new world of grow media for you to choose from.
So what is a growing medium? Aside from an adolescent psychic, growing mediums are the soil substitutes used in hydroponics, such as soilless potting mix, perlite, or coco coir, that support your root system and retain nutrients. Each type has different properties but the most important characteristics to consider are water retention, aeration, and pH neutrality. There’s an overwhelming number of medium types and recipe mixes, so let’s go over the most popular media.

Maybe they just have a song in their wires? In all seriousness, humming or buzzing in your lights can be maddening. Whether it’s coming from incandescents, fluorescents, or LEDs, the problem usually stems from vibration caused by the voltage applied. The vibration itself isn’t always the fault of the bulb either, other devices on the same electrical line can lead to noisy lines or noisy light bulbs too. Usually, this hum is a fairly easy fix so long as you know what to look for, which is great since this is a common problem.

Water is vital for life as we know it. With the exception of certain types of microbes, everything on earth needs water to survive and requires it to thrive. But just as there are many different types of living things on Earth, the type of water needed (mostly what’s dissolved in the water) varies from organism to organism. The water you need for drinking and the water you use on your plants for nourishment are, by necessity, different. Take a look at where your water comes from, what could be in your water, and how you can find out for yourself.
