Temperature and Humidity Control

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.

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.
