Tips for Growing Mr. Nice Cannabis

Ever wanted to grow your favorite strain? Leafly and General Hydroponics are teaming up on a series of grow guides that will equip you with all the tips and tricks you need to grow different strains successfully.


Strain Overview: Named after a famous cannabis smuggler, Mr. Nice is a cross between G13 and Hash Plant. Originally, this strain by Sensi Seeds was not around for long, but it was brought back in 1999 and has been a staple ever since. This plant produces extremely dense, resinous buds with a sweet, earthy aroma. Its heavy effects are best put to use before a nap or big meal.

Grow Techniques: An indoor hydroponic or soil setup offers the best results. The dense plant should be topped early on to promote even growth, and then pruned heavily to keep foliage away from the base of the plant. Cleaning up this undergrowth helps keeps pests under control and will direct the plant’s energy to the top of the canopy. 

Flowering Time: 8-9 weeks 

Yield: High 

Grow Difficulty: Moderate

Climate: Humidity and moisture will cause bud rot, so don’t let this plant sit in the rain. Colder temperatures before flowering will increase the resin production, but generally speaking Mr. Nice prefers a temperature between 65 and 80 degrees Fahrenheit.

Indoor/Outdoor: Mr. Nice grows well in both indoor and outdoor gardens. However, this strain should be grown in a dry climate outdoors or in a greenhouse. 

Feeding: Heavy feeding will bring this plant to its full potential.
