To create this standout, Critical Lee crossed his best Critical Mass with a Critical + that was selected specifically for its distinctive Blackberry taste and smell. Due to Monster Mass Seeds' height & branchiness, these ladies are best kept outdoors, but with careful training, their extreme vigour can be tamed just enough to bring them inside. Either way, you can expect a potent windfall with stash-busting yields and bone-rattling 20% THC levels.

Thanks to their impressive speed, Monster Mass Feminized Seeds rarely have a problem with mould or mildew, but you should keep the humidity levels low & circulation fairly high just to be safe. Once cured, these cannabis seeds have a nearly overwhelming aroma that mixes Blackberry with pungent Skunk while the taste is sweet & fruity with clear notes of Kush, Skunk, Blackberry & even a little Cola. Yum!

Monster Mass Seeds are a high-yielding blend of classic Critical Mass and an extra-fruity Critical + strain. The breeder recommends outdoors for this impressive cannabis seed due to its huge size & branchy structure. When kept indoors, early FIMing and other training methods are a must. In either case, you will not be disappointed in the yield - it's outstanding!

Once you make the flip, Monster Mass will be ready in a mere 45 to 50 days (just 7 weeks). Dried, you can't beat the complex flavour profile or the amazing bag appeal. Think large, round, pale-green buds that shimmer with gold dust & goo followed by a taste that coats your mouth in sweet fruit flavours - delicious!
