Project Blue Book Feminised

Project Blue Book is bought for what comes off it, and the sourced figures are up to 450 g/m2 under lights and up to 500 g/plant from a plant grown out. Those are ceilings, not promises — pot volume, light intensity and how honestly you feed decide where you land inside them. Run the numbers for your own tent with the yield calculator before committing to a pack size, and put it next to the rest of the high-yield strains if weight is the whole point.

What the sourced data gives for this cultivar: up to 450 g/m2 under lights, up to 500 g/plant from a plant grown outside. Reaching either is an environment problem before it is a genetics one.

Root volume sets the ceiling before a single flower forms. Under-pot a plant and no feeding schedule rescues it. Get the container right early and the plant does the rest.

Light is the second lever, and the one most growers get wrong in both directions — too little through veg, too much in late flower where it bleaches rather than builds. Steady beats aggressive.

The third is the fortnight around the flip. The stretch after the flip decides your final canopy shape, and it is the last moment training does anything useful.

Feed to the plant rather than the calendar. Our nutrient calculator gives a starting schedule; the plant will tell you where it is wrong. Worth a side-by-side comparison before you commit if weight is the deciding factor.

Reported effects cluster around happy, energetic, creative. At 20% THC that is a meaningful figure rather than a decorative one, and the sensible approach with anything in this range is to start lower than you think and wait longer than feels necessary.

The 12/88 balance shapes where it lands: head-forward and clear enough for daytime, though the ceiling arrives faster than beginners expect. Tolerance moves this more than any other variable, which is why two people describe the same jar differently.

Prefer something gentler? The CBD-forward strains range trades peak potency for balance.

Limonene leads, terpinolene sits behind it, and pinene runs underneath.

This trio is a common signature in well-regarded cultivars, which is not an accident: limonene carries weight, terpinolene adds definition, pinene keeps it from being one-note. It reads clearly on a first opening rather than needing to be hunted for.

Project Blue Book is rated moderate. That sits in the middle — you want a working understanding of pH and feeding, but nothing exotic. Being a photoperiod means you decide when it flowers, and therefore how big it gets.

Shipped nationwide in plain packaging. Every strain page carries whatever grow data we could actually source, and nothing we could not.
