Cannabis Cultivation Guides

Cannabis nanners are exposed anthers, the small banana-shaped, pollen-bearing parts of a male flower, growing straight out of a female plant's buds. They're a sign of hermaphroditism, usually triggered…

Manifolding cannabis means topping a young plant and training it into one central hub with equal-length arms, so every branch ends in a cola of similar size. Most growers use the terms “manifolding" and…

ScrOG or Screen of Green is a method that trains cannabis plants to grow horizontally across a mesh screen or scrOG net instead of letting them climb vertically. The objective is a flat, evenly lit canopy…

A cannabis leaf symptom chart links what you see on a leaf, and where it shows up on the plant, to the problems most likely behind it. Leaves are usually where trouble shows first, whether it comes from…

Knowing when to transplant cannabis comes down to looking at the roots. Move seedlings once roots reach the drainage holes and they have 3–5 sets of true leaves. Move clones once 1- to 2-inch white roots…

Plant growth regulators (PGRs) are natural or synthetic substances that change plant hormone activity to manipulate growth, development, and flowering. In cannabis cultivation, PGRs are used commercially…

Knowing how to get rid of leaf miners on cannabis starts with confirming the damage: check leaves for see-through tunnels that widen from one end, often with a dark line of droppings. Then pinch each tunnel…

Hop latent viroid (HLVd) is a tiny strand of infectious RNA that causes dudding disease in cannabis. Infected plants and clones show severely stunted growth and shrunken buds with diminished yields and…

The best cannabis pH level for soil is 6.0–6.3 (5.5–6.5 acceptable) and 5.8–6.2 (5.6–6.4 acceptable) for coco coir and hydroponic setups. Keep root zone pH inside those windows and your plants can take…

Lollipopping weed means pruning away shaded growth like smaller bud sites, branches, and leaves on the lower part of a cannabis plant so more of its energy goes to the bud sites up top. Those low sites…

The Sea of Green method takes lots of small cannabis plants, flips them to flower after a quick veg, and lets each one finish with a single cola. Most growers call it SOG for short, and it's one of the…

To clone marijuana, cut a 4–6 inch shoot from a healthy female plant in veg, just below a node. Strip the lower leaves, dip the base in rooting hormone, and set it in a damp medium under a humidity dome…

Flushing cannabis is about switching to plain, pH-adjusted water in late flower instead of nutrient solution. Count back from your expected harvest date so the flush wraps up as the trichomes turn mostly…

White mold on plants is likely powdery mildew on cannabis — a fungus that leaves dusty white to pale-gray patches on leaves. Confirm it by wiping a patch, then remove infected leaves, improve airflow and…

Cannabis foxtailing is when buds grow upward instead of filling out, pushing narrow, spiky towers of new calyxes off the top of a cola until it looks like a cluster of fingers or a fox’s tail. It has three…

New leaves with dark bluish purple tones, bright yellowing tips, and a metallic-looking sheen are classic symptoms of copper deficiency in cannabis. It looks alarming, though it’s actually quite uncommon…

A cannabis boron deficiency shows up in the newest growth first, twisting the tips and dotting young leaves with brown or yellow spots, often with brittle stems. It stays rare, because most tap water and…

Zinc deficiency in cannabis shows up as yellowing new leaves, paired with shrinking, twisted blades, and tightly bunched nodes. Left uncorrected, it stunts plant growth, leading to deformed buds that lack…
