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).

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.

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.

December 12th is honored as National Poinsettia Day, and with it just having passed us, I imagine a quick glance around your home will reveal at least one of these beautiful plants sitting in splendor on a window sill. It may surprise you to learn that these beautiful holiday plants are actually small trees, not flowers. The blooms on these plants are very small and unattractive, but it’s the bright red bracts (modified leaves) that attract insects for pollination and entice us to decorate our homes with this festive shrub. With proper care, they won’t just give you a beautiful winter, but they can grace your home with vibrant colors next year too.

All plants grow at different rates based on soil and food supply. Nutrition and climate can also affect the size of plants, giving you more or less space to work within. Agricultural chemicals like plant boosters are used to artificially encourage or discourage growth, but it’s possible to get the same results by simply managing your plants’ lighting and temperature through temperature differential (DIF) control. By creating a temperature difference between the night and day grow cycles you can effectively control the size and yields of your plants.

We’ve mentioned water and soil pH many times before in previous hydroponics articles. But we’ve never really covered why pH values are important or how they affect your plants. So today, let’s break out some light chemistry and go over what a pH value is and how you can balance it for healthier plants.
