Using this glossary
What are the most important aquascaping terms to learn first?
Hardscape, substrate and carpet cover most early conversations. Hardscape is the rock and wood that sets the structure, substrate is what the plants root into, and a carpet is the low, spreading planting across the floor of the tank.
Do I need to know the Latin plant names?
Not to get started, but they help when you buy. Trade names vary between shops and some plants are sold under more than one name, so the Latin binomial is the reliable way to check you are getting the species you meant to buy.
Where should a complete beginner start?
