Seed and Grow Guides
16 guides on picking a seed, keeping it, and growing it out. Every claim about flowering time, price or potency is checked against the 384 strains in this index, so where the usual advice and the catalogue disagree, both are here.
Choosing seeds
What the words on a listing mean, and which of them predict anything about the plant you end up with.
-
Seed Types: Feminized, Autoflower and Regular
What the seed type decides: sex, what triggers flowering, and how long it all takes, with the flowering times and prices of the strains indexed here.
-
Flavour and Terpenes
Sweet, citrus, earthy: where the flavour words come from, which terpenes they point at, and what the research does and does not support.
-
Indica, Sativa and Hybrid
The labels stopped being botany decades ago. What genetics found, and what the words still predict about the plant you are about to buy.
-
THC and CBD Numbers
A percentage on a listing is a claim about a plant that does not exist yet. What the figure describes, and how far it drifts.
Buying and starting seeds
What a seed actually costs, how to keep the ones you are not sprouting yet, and how to get the rest going.
-
Buying From a Seed Bank
Shipping, payment and packaging: what a seed bank adds to the price on the listing, and what to have in front of you before you order.
-
Germinating Seeds
What a seed needs to sprout, the three ways of giving it that, and how to tell a dead seed from a slow one.
-
Storing Seeds
Cool, dark and dry, why the refrigerator beats the freezer, and what age does to germination rates.
-
What a Seed Costs
Pack sizes hide the price. What a single seed costs across this index, where the differences come from, and what a listing never tells you.
Growing
From a seed on a plate to jars on a shelf, and what to check when something looks wrong.
-
Harvest, Drying and Curing
When to cut, why a slow cool dry keeps the smell, and what two weeks in a jar actually change.
-
Indoor Growing
Light, air, water and feed, in the order they decide the outcome. Why wattage is the wrong number and overwatering the most common mistake.
-
Growing Outdoors
Latitude sets the flowering date and the weather sets the deadline. Choosing a strain that finishes before autumn does.
-
When Things Go Wrong
Most symptoms are water, pH or overfeeding rather than a missing nutrient. A working order of checks.
Space and yield
How tall a plant gets, how to keep it inside the space you have, and what actually decides how much it produces.
-
Height and Space
The trait that can end a grow outright, the stretch people forget, and how to keep a plant under the lamp.
-
Pots and Root Space
A plant grows to the size its roots can support. Pot volume, fabric against plastic, and what a container costs you in height.
-
Training and Pruning
A lamp lights an area, not a plant. Bending, topping and screens, and when to leave a plant alone.
-
Yield Labels
Heavy, large, XXL: no standard sits behind those words. What actually decides how much a plant produces.
