    How To: Choosing a Fan

    Fans might not be as grand as your growth system, they may not be as alchemically appealing as brewing up nutrient solutions and they’re definitely not as sexy as reflectors (just me then?); but they are undeniably essential.

    Getting your extraction system right takes a little maths and a little time, which can be galling to newcomers. But never fear, HYDROMAG is here to break it down into bite sized chunks and hold your hand through the vaguely traumatic process.

    To start with, you could do with a basic understanding of the habits of air and its relation to temperature and high and low pressure within the Earth’s atmosphere; or you could just take it as read that hot air goes up and cold air goes down. Your bulbs give off heat, which you want to reduce, so it helps to have your extractor fan near your bulbs. Common practice see’s most people placing extraction at the top of the room, and the intake towards the bottom.

    Hydro in Hell's Kitchen

    The tree or plant is an obvious metaphor for personal development through education. Many schools use tree iconography as part of their crest design. As Aristotle once said, “the roots of education are bitter, but the fruit is sweet”

    The learning process can be difficult – tedious even – but the years of toil are worth it when the reward is a sweet, juicy rounded intellect and a delicious plump repository of knowledge. But here at HYDROMAG our staff are all alexithymic and therefore incapable of understanding metaphor. So when we saw this quote from John W. Gardner (former Secretary of Education under President Lyndon B. Johnson): “Much education today is monumentally ineffective. All too often we are giving young people cut flowers when we should be teaching them to grow their own plants,” we thought he was being literal. But we’re not the only ones – the Food and Finance High School of Hell’s Kitchen, New York, (possibly stung by Gardner’s criticism), is teaching pupils Hydroponics, Aquaculture and Aquaponics.

    Edible Food Packaging

    The world of food packaging has gone through a number of fundamental changes over the past twenty years. Gone are the rows and rows of aluminium tins from our supermarket shelves. In their place paper and plastic have arisen, albeit adorned with the same vibrantly coloured and grossly misleading branding that has governed our buying habits for half a century. As the urban populations of the world have grown, so too has humanity’s predilection for pre-packaged foodstuffs, lazily conditioned into a vague facsimile of an actual meal. Invariably this increased popularity has led to a relative increase in discarded plastic.

    Britons are, relatively speaking, pretty good at recycling, We’re by no means the best at it, and the lack of recycling facilities on our own shores does rather negate all our hard work by requiring petrol fuel vehicles to ship our waste abroad, but that’s an argument for another day. And so the question of how we package our food remains an ever present spectre hanging over our increasingly ecofriendly society.

    Growing in a Sealed Environment

    The Key to good gardening is to simply let the plants grow, or so a great man once told me. An insightful and poetic mantra indeed, but entirely lost on me at the time, due to fact that I was seven years old. From every cold frame at the bottom of the garden to the glorious heights of The Eden project, when it comes down to it, we’re all doing the same thing- setting the stage as best we can to allow plants to do that thing that they do so well.

    Indoor gardening and hydroponics offer us a greater level of control than traditional gardening, and growing in a sealed environment takes that control even further. Think of sealed growrooms as your very own, self-contained biomes. Beyond environmental omnipotence, sealed growrooms are ideal for introducing CO2 controls and require minimal extraction. Naturally there are downsides too; Sealed growrooms are expensive, both to set up and to run. If you are planning to venture down that road, here’s HYDROMAG’s guide to doing so.

    How It Works: Carbon Filters

    Welcome friend, to a corner-stone in HYDROMAG’S constant progression and evolution. As a devoted reader I’m sure you are aware that we like to provide you lot with more than the usual rhetoric on products you generally may otherwise come across. We don’t slyly focus more on particular sets of products because we have vested interests in their promotion and sales, or produce articles that are heavily biased to a particular type of theory, that tailors your choice towards a particular product. Even though we are an advert funded magazine, we like to keep everything nicely balanced, even if it does annoy our sponsors.
    We generally don’t do things by halves either, so rather than get just one person’s take on something, we like to go all-out and get at least three. That way we can be nice and fair and give multiple manufacturers a platform to extol the virtues of the theory behind their products. This in turn gives you the opportunity to get a take on a subject that involves multiple people’s opinions and doesn’t pigeon-hole your thinking down any particular avenue.
