Frequently Asked Questions

Is White Widow + suitable for beginners?

Yes, its high resistance to pests and mold, combined with a forgiving nature, makes it an excellent choice for novice growers looking for heavy yields without the headache.

How does it differ from the original White Widow?

By crossing it with Critical Mass, Original Sensible Seeds increased the overall yield, boosted the THC levels up to 22%, and shortened the flowering time slightly, without losing the iconic resin production.

Can I grow this strain outdoors in colder climates?

Absolutely. Because it finishes flowering by late September or early October, you can usually harvest before the heavy autumn rains and frosts set in, minimizing the risk of bud rot.

Personal Experience of Pevgrow’s CEO (Alan)

Whenever someone asks me for a foolproof strain that delivers commercial weight without sacrificing that classic Amsterdam coffee shop vibe, I always point them to White Widow +. In my own tents, this plant is an absolute beast. The Critical Mass genetics really shine through in the vegetative stage, creating thick, sturdy branches that can actually hold the weight of those massive colas later on. I usually run it in a SCROG setup, and the canopy fills out incredibly fast.

What I love most is the resin production. By week six of flowering, the buds look like they’ve been rolled in powdered sugar, and the smell is this intense mix of earthy pine and sharp citrus. It’s a breeze to trim, and the final product hits like a freight train—starting with a massive euphoric rush before melting you into the couch. It’s a staple in my rotation because it simply never disappoints, whether you're extracting or just enjoying a classic joint.
