Grow Tent Upgrade!

"Growing plants prefer relative humidity levels of around 60%. "

You've probably read that factoid, or a variant of it, many times. It's repeated often, especially by indoor gardeners seeking to create the perfect environment for their growing plants.

But what do you do if your hygrometer (i.e. your instrument for measuring relative humidity) reads 30% or 40%? Your plants' leaves are curling upwards like taco shells. You keep spraying them . .. but nothing seems to be working, смотрите humidifier in grow tent. So what can you do about low relative humidity in your indoor garden?

Plants suck up a lot of water—but very little of it (less than five percent) is actually retained for building new cells etc. The vast majority simply passes through your plant—sucked up by the roots, suffused through the vascular structure of your plant, and finally exiting through tiny holes in the leaves called stomata. Just like in a car's engine, water is primarily used by plants as a coolant.

Dry, low relative humidity air creates what is known as a high vapor pressure deficit (or VPD) - basically, the inside of a plant's leaves are full of moisture. If, somehow, you could measure the relative humidity inside a tiny pocket of air inside the leaf, it would read 100%. It's wet in there! And that's all good.

However, as we've already pointed out, plants need to breath (exchange gases) through tiny holes. This exposes the plant to the outside world. If this outside world is dry, the plant has to suck up more moisture to combat the drying effect—thus making it work harder, just to stay alive. Dry, arid conditions are also perfect for nasty bugs such as spider mites. Dessication (drying to the point of cellular damage) also opens up your plants to potential attack from mildew and other pathogenic molds.



Ever wondered why growers start their seedlings inside propagators? Wonder no more! The propagator seals in moisture creating a high relative humidity environment. This means your tiny, tender little seedlings can Фокус on the task of growing without their miniscule root systems getting stressed out with having to provide too much moisture to those young leaves. But what happens when your plants outgrow the propagator?

Here's a simple propagation set up. The grow tent pictured above is a HOMEbox Clonebox View—ideal for starting your cuttings and seedlings. An adjustable extractor with built-in thermostat controls the temperature by pulling out the hot air. It's vented into an airy loft space.

The blue bucket sat on top of the tent contains water. The yellow hosepipe is fed into the grow tent to a humidifier.
