Description
Built on a Z x ZBX lineage, Heavy Z Feminised Seeds from James Loud Genetics represent a deliberate backcross designed to intensify and refine the Z genetic profile. The aroma is the centrepiece here: candy cane and candy corn up front, followed by melon syrup and a clean citrus lift that keeps the nose engaged from veg through cure. Effects carry the balanced character you'd expect from an indica-sativa hybrid, settling into something both grounded and clear-headed.
As a feminised photoperiod variety, Heavy Z gives growers full control over the vegetative window before flipping to flower. The 7 to 9 week flowering time suits both dedicated grow rooms and well-managed tent setups, with the shorter end of that range accessible to growers dialling in their environment. Plants reach a medium height, manageable with light training. Yields trend toward the modest side, a worthwhile trade for the terpene density and phenotypic range this cross produces. James Loud Genetics recommends this one for experienced cultivators comfortable working with Z-heavy structure, and the diversity of expressions across a pack makes it a genuine pheno-hunter's project.

about this product
Heavy Z by James Loud Genetics delivers a candy-forward Z backcross with complex citrus and melon aromas, ready for growers who want serious terpene depth without serious difficulty.
The aroma is built around candy cane and candy corn up front, layering into melon syrup and a bright citrus finish that develops from veg all the way through cure. It's a complex, terpene-forward profile rooted in the Z genetic line and refined through deliberate backcrossing by James Loud Genetics. Expect that sweetness to carry through to the flavour with a mild chem edge underneath.
Heavy Z sits in the easy-to-moderate range, making it a solid choice for first or second-time growers who want something rewarding without an unforgiving learning curve. As a feminised photoperiod variety, it gives you full control over the vegetative period so you can let the plant develop at your own pace before flipping to flower. The medium height also keeps canopy management straightforward in most setups.
Indoor growers can expect around 350–450 grams per square metre over a flowering window of seven to nine weeks. Per-plant yields come in at 200–450 grams depending on how much veg time you give and how well conditions are dialled in. It's an average-yield variety, so the real draw here is the quality of the terpene profile rather than chasing maximum weight.
Heavy Z sits in balanced indica-sativa territory, producing effects that are both relaxing and uplifting without leaning hard into either extreme. THC runs between 16 and 24 percent, so expect a noticeable, grounded experience that stays clear-headed rather than couch-locking. It's the kind of high that suits end-of-day use without completely switching you off.
