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.
Is your back aching from lugging endless sacks of soil, coco or other growth media in and out of your indoor garden? Then check out our latest blueprint, aptly named “The Water Room.” The idea is to grow monster tomato plants directly in a nutrient solution using a cutting-edge, modular Deep Water Culture (DWC) system called The Under Current™. But the liquid theme doesn’t end there. Water is also used to cool the garden using an ingenious chiller-based system created by Hydro Innovations.
Michael Christian, an expert consultant to the commercial hydroponics industry, shares his insights into recirculating nutrients effectively to achieve high performance plant growth while conserving water and nutrients.
The Top 10 Mistakes That Drag Your Yields Down: Everest shares some time-honored heuristics to help beginner growers increase the productivity of their indoor gardens.
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.
Nutrient guru Lawrence Brooke of General Hydroponics takes us through some of the critical factors that have a direct bearing on the effectiveness of our nutrients.
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?
Summer can present a real challenge for indoor gardeners. The obvious heat-beating tactic is to install an air-conditioning system. But this just isn’t feasible or desirable for everyone. Urban Garden Magazine explores air-cooled lighting and other options.
Want to push the envelope? Bust open your boundaries? Top your personal best? Okay, so you might have nodded ‘yeah yeah’ to that string of rhetoric – but, in this section, we’re going to actually show you how to do it. First up, we’re going to take a look at “side lighting” – what it is, how to go about it, and why thinking like a Martian can be quite helpful.
The cost of setting up an indoor garden can vary enormously. Basic set-ups can fall within most people’s budgets, whereas more advanced operations can see costs quickly mount up … and that’s without the addition of fancy control gear! So are these “smart boxes” really necessary for the hobbyist indoor grower or are they just for the pros – the control freaks? Jeff Broad, designer of the IntelliClimate, reveals all.
