Climate Management

Cli-mate joins the GrowLED catalogue with fifteen controllers, from a speed controller at 50,90 € to a station driving lighting, temperature and humidity. I go through the four families, compatibility with Prima Klima extractors and an honest comparison against GSE.

Every winter, I get the same messages: "my tent dropped to 12°C last night" or "my plants have stalled since the season changed". Cold isn't handled at random, you measure it, heat against it and regulate it in that precise order. Here's the method I use myself, step by step, with the tools that genuinely make a difference.

Humidity is the parameter most growers discover too late, once the leaves crisp up or the first spots of mould appear on a tight bud. In this article I show you how to measure your tent's humidity properly, how to correct it either way depending on what you read, and how to automate the whole thing so you never have to think about it every evening again.

A well tuned tent doesn't need watching by the hour, it runs itself. Timer, thermostat, hygrostat: three families of automation which, put end to end, turn a grow you constantly correct into one that regulates itself while you sleep, work or are away.

In a grow tent, temperature is never a figure that stands on its own: it comes from a constant balance between the heat given off by the lighting, the speed at which the air circulates and the structure's ability to expel the surplus. Joseph, expert grower at GrowLED, explains how to measure, regulate and correct that trio.

How to automate your grow tent's extraction, ventilation and humidity before you leave on holiday, without false promises about watering.

High heat? Joseph, GrowLED grower, shares his 5 field-tested reflexes to keep your tent's temperature in check and protect your harvest.

Small, discreet, essential: Joseph explains why the clip fan is the first climate accessory to install, and how to choose the right one.

Undersize your extractor fan and heat builds up; oversize it and humidity collapses. Joseph shows you the exact calculation he uses in the field, volume by volume, plus the three traps that skew the result.
