Every ColaXpress teaching image, in one place.

They follow the run, and you will want them at different moments.

The galleries below are ordered the way a grow happens rather than by size. Equipment is the one to open before anything is running, while you are still deciding what to buy and where it goes — it is mostly diagrams and comparisons, and it answers questions about proportion and priority that are hard to settle in words. Troubleshooting is the largest by a distance and the one you will reach for under pressure, when something has changed overnight and you need to name it before you act. Harvest & Trichomes covers the single irreversible decision in the whole process, and it repays being studied early, before the pressure of the actual call. Drying & Curing covers the stretch where a good harvest is most easily lost, and it is the group most worth reading in advance rather than during.

If you are new and want one place to start, start with equipment and read the ranked boards. If a plant is already in trouble, skip straight to the troubleshooting set or work the symptom from the diagnostic entry point instead.

Growing is a visual skill, and prose is bad at colour, texture and proportion.

Written instructions handle procedure well and appearance badly. A guide can tell you that magnesium yellows the tissue between the veins while the veins themselves stay green, and that sentence is accurate, and you will still stand in front of your plant unsure whether what you are looking at counts. The same gap opens at every visual decision in a grow: how milky is milky, how brown is too brown, what does a stem that is genuinely ready actually do in your fingers. Those questions are settled by comparison, not description.

So every teaching image on the site is collected here, grouped and captioned, in a form you can scroll while standing at the cabinet. Nothing in these galleries is decorative and nothing is stock photography imported to fill space — each frame was made to answer a specific question in a specific guide, and each tile links back to the guide it belongs to. The library is a second way into the same material: instead of reading a page and hoping the picture matches, you find the picture and follow it back to the explanation.

Three habits that make a comparison worth something.

A visual reference only helps if you use it honestly, and there are a few predictable ways to use it badly. These are the ones worth guarding against.

• Compare in the same light. Grow lights flatter a plant in ways that make trichomes, colour and mold all read wrong. Take the leaf or the bud out to neutral light before you decide what you are looking at.
• Match the whole pattern, not one detail. A single yellow leaf, a single amber head, a single brown spot means very little on its own. What you are matching is where the damage sits, how much of the plant is involved, and what the surface is doing.
• Follow the link under the image. A picture can tell you what you are seeing; it cannot tell you what to do next. The guide behind each tile is where the response lives, and that is the half that actually changes the outcome.

The library grows as the guides do, so a symptom or a stage that is not here yet may well be next time. If you cannot find what you are after visually, the site search covers the same ground in text.
