About Firefly
Firefly pairs Double Dutch with Cinderella 99 into a 70% indica hybrid from Mosca Seeds, an easy plant to grow that stays compact at 90-120cm indoors while still returning 400-450 g/m2. Flowering wraps in 8 to 9 weeks, a standard window that doesn't ask for special patience. THC has tested up to 24%, genuinely strong for a strain rated this easy to raise, which makes it an appealing option for growers who want serious potency without a difficult grow. The Cinderella 99 in its background likely accounts for some of that strength, paired with Double Dutch to round out a hybrid built for both convenience and a real kick.
