How Do I Setup Greenhouse Ventilation?

Jan 26, 15 How Do I Setup Greenhouse Ventilation?

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).

5 Common LED Questions

Jan 19, 15 5 Common LED Questions

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.

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.

Dec 29, 14 How Water Quality Affects Your Plants

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.
