As we’ve learned in parts 1 and 2 of this series, in order to grow successfully in a hydroponic system, there are certain basics that always need to be kept in check, otherwise plant performance inevitably suffers. After covering source water, nutrient and pH, world-renowned hydroponics expert Michael Christan breaks down the final ingredients of a healthy indoor growing environment: oxygen, light, temperature, humidity, air circulation and CO2.
“Grow your own food!” is easy to say, but what exactly do you need to do to make that happen? We asked the indoor garden and greenhouse design and construction experts at Good Green Builders to draw us up a plan of a greenhouse that could feed not just one, but four families! So if the initial set-up costs of a family food production facility seem prohibitive, why not collaborate with your friends, split the investment, and enjoy the harvest together. Happy days!
A sealed room is an indoor garden that is totally … you’ve guessed it … sealed. I’m not just talking about light proofing here. I mean air-sealed. There are no holes, gaps or vents to anything outside of the indoor garden. The aim of the game here is to create a totally controlled environment where every aspect of the plant’s production can be manipulated and customized to produce the optimum results.
We asked two experienced growers (Dan from Oregon and Fred from The Netherlands) to face off with their different opinions on how to calculate your fan requirements. Whose method do you think is best?
