Indoor growing guide

As soon as watering comes up, the talk turns to reverse osmosis units, TDS meters and thermometers. After years fixing watering routines in the field, Joseph shifts the question: once the water is prepared, how do you get it to the root without spoiling it, and at the right moment?

A plant that yellows, stalls or burns at the tips often has a pH or EC problem that was never checked. Joseph explains how to measure, calibrate and correct both, using the kit he actually relies on for his own grow.

Three letters, three numbers, and yet half of the burnt leaves I come across come from a badly read label, not a bad fertiliser. Here I show you how to decode an NPK, why two products with similar ratios can need doses ten times apart, and how to feed without overloading your plants.

People often ask me why I focus on what happens below the pot rather than above it. The answer: a plant never feeds itself alone, it delegates part of the work to fungi and bacteria settled around its roots. Here I break down that living partnership and where each product fits.

A failed cutting is almost always about overlooked details: the wrong moment to cut, a medium too loaded with salts, humidity that collapses on the first evening. Here is the method I use in my own grows, step by step, with the concrete markers that make all the difference between a clone that stalls and one that comes back strong.

The complete, honest guide to the gear that actually matters, item by item, to nail your first indoor grow with confidence and without blowing the budget.

After fifteen years growing under HPS and guiding hundreds of GrowLED customers through the switch to horticultural LED, I still see the same hesitations: watts, equivalences, spectrum, heat. This article goes through, point by point, what actually changes when you leave a high pressure sodium bulb behind.

Choosing a grow tent isn't only about size. It's a balance between the number of plants, the real quality of the fabric and structure, and the ceiling height you actually have at home. Joseph shares the concrete markers he uses, figures in hand, to pick the right one.

For a successful wintering of your plants, suitable LED lighting is essential to compensate for the lack of natural light. GrowLED offers ideal solutions: the SpectraBULB X20 bulb for small areas up to 1 m², and the SpectraBULB X30 for large plants such as lemon trees. The FloraCLIP , an E27 compatible clamp, makes their installation easier. For larger areas, the SpectraB2G X45 and X90 bars provide uniform lighting up to 160 cm x 100 cm. With this equipment, your plants will stay healthy all...

This article discusses the materials needed for indoor cultivation. Indoor cultivation has recently become a popular hobby, offering many advantages such as the ability to control the environment and the absence of weather-related problems. To successfully sow seeds in indoor cultivation, certain materials are needed, such as lighting, heating, greenhouses, substrates, and accessories. LED lighting is essential for the growth of plants indoors, while heating helps keep the temperature at an...

The fluorescent lamps are a popular lighting choice for indoor cultivation due to their low heat emission and affordable price. However, they have a disadvantage in terms of lifespan compared to LED lamps and do not provide the same savings. Many cultivators prefer to use LED lighting for more reliability. Fluorescent lamps work by using pressurized gases such as mercury vapor, neon, xenon, argon or Krypton in a tube. It is important to store them in a safe place to avoid any environmental...

The article discusses indoor growing, which involves growing plants in an enclosed space, usually inside the house. This requires basic equipment such as horticultural LED lamps for artificial lighting, an irrigation system, pots and an air extractor. Indoor growing can be done all year round, allows for control of plant growing conditions, can be a relaxing activity and can lead to high quality crops. However, growing indoors can also be expensive, require a lot of space and be demanding in...
