Critical Mass by Mr Nice Seeds is a regular cannabis seed that has its origins in the cross of an Afghani and a Skunk #1. Being so easy to grow and heavy-yielding, no wonder commercial users love it that much.

The flavour and aroma of Critical Mass are pronounced and fruity, with clear hints of lemon and pine wood. It provides a heavy mental and physical effect.

Remember that, besides our catalogue of Mr.Nice, you can access our selection of over 3,000 cannabis seeds. Don't forget to use our advanced filters to help you find strains with higher or lower THC levels, with faster flowering cycles and of varying sizes depending on your grow's needs.
