Description

Fast White Widow strain glistens with trichomes.

This fast White Widow maintains frosty White buds from the indian x Brazilian parentage, just for those of the impatient amongst us we have shaved a week off the flowering time. You can still expect dense trichome colvered buds that glisten along with a sweet, sugarly look & taste. Its just there that much quicker now.

Grow guide

Early/Fast outdoor timeline

Fast / Early strains keep the photoperiod growth pattern, but they begin flowering earlier and usually finish sooner — helping outdoor growers harvest before late-season weather becomes a problem.

Stage 1

Germination / Early Start

March – April

Wait for: warmer days, lower frost risk, stable spring weather

Watch for: cold snaps, excess moisture, slow early growth

Stage 2

Seedling / Transplant

May

Wait for: steady light, mild conditions, protected early growth

Watch for: transplant stress, pests, wind exposure

Stage 3

Vegetative Growth

June – July

Wait for: long bright days, healthy expansion, strong structure

Watch for: overcrowding, nutrient issues, insect pressure

Stage 4

Flowering

From late July

Wait for: first signs of bloom, good airflow, settled conditions

Watch for: humidity, mould pressure, poor weather

Stage 5

Harvest

From early September

Wait for: ripe trichomes, dense finished flowers, harvest readiness

Watch for: cutting too early, rain, bud rot

Indoor Early/Fast timeline

Fast / Early strains are most valuable outdoors, where earlier flowering and shorter bloom times help growers harvest before poor autumn weather. Indoors, their main benefit is a faster flowering phase than photoperiod versions.

Popped all 3 seeda looking for a good pheno. The one I kept grew very fast in veg under cmh.. it didn't like moisture much so it was drier soil and heavy humidity to get the veg complete quick. Thick stalk i juiced up my silica calcium and mag few weeks before flower to build thickness. I've done fast strains before so I read all my notes from past grows to see what an actual fast flowers performance should look like week by week. About 10 days for buds to start forming and 3 weeks I had good stretch and thick clunkers on my stalks. Great terp development, I added in some uvb about week 5 for 5 hrs a day to include some spectrum stresses and all worked out well for me. I use a total vegan style feed so my flavors fawking popped on this one. Buds came out like big rocks with snow covering them. Got the drying down to 10% moisture and started curing. Took longer than most due to the density and structure of the flower. Very good results. Im throwing 1500ppm of c02 in the next cycle I run with this one see if i can get more than 2g a watt. 8 out of 10 but I've lived in Hawaii and Cali so my taste is picky.
