Mixed Feelings

By Jamie MI Brenner on February 18, 2019

I received this clone by accident. While it is a really cool plant, intense deep purples, really good smell, I am torn. It is a very short plant, and yielded pretty low, and on top of this the thc content in the bud feels pretty minimal, the other DHN strains I had in the same tent knock me on my ass so I think it’s the genetics in this one. It is a really cool, unique strain, but it’s a gimmick, there are certainly more solid genetics out there.

Amazing Unique Strain

By JustAFarmer on October 24, 2018

This strain is an absolute keeper if you enjoy a fast finishing very unique strain. The aroma is like nothing else. I describe is a strong blueberry muffin smell with a faint hint of the old school baby shit strain that was around during the 90’s. I grew this indoors with daytime temps around 79-80 and nighttime temps around 70-71. The results was a beautiful purple plant that just kept getting more purple after about 50 days. Chopped mine at day 60 from 12/12. This strain is a connoisseurs delight and a keeper for me.

Grows evenly, but stock zig zags which can cause side heaviness depending on flower formation and branch twist, leads to leaning.

Very fast vegetation stage 1.5 months until pre flower, really fast at 12 on, 12 off light/dep.

Bud formation beaitiful, but really gotta watch for mold as it is a tight plump flower and the lighter green color strains seem more prone to mold than the darker green color strains.

Purple bracts/nodes make it more important to keep a close eye for final day prior to harvest.

In hot conditions, cut water last 2-3 days before harvest.

In moist and cooler conditions, cut water 1 week before harvest.

Hot weather daily water

Cooler weather water twice per week.

A less moist soil seems to suit this strain well.

To get this strain to grow larger, must have 16 on, 8 off. Once 12/12 is set, Blueberry Muffin goes to flower. It must be a heavy indoor strain crossed for light dep with an outdoor strain, not sure.

Growth rate of BM versus GSC is about 2-3 weeks difference.

Brown hair coverage, not sure if 50% or 75% on this strain to harvest, but will find out at some point.

Seems to have less small wasteful bud formation with better popcorn formation at bottom areas of stock.

Tempted to thin majority of water leaves in last week….please advise if this is not recommended. It seems to work great on other strains in last week after cutting water, and flowers suck more from stock up, and lower moisture content in flower, like a live dehydration.

Be careful of preflower outside!

By Drew on September 26, 2018

This is a great strain. However I gave it 4 stars because it is quite finicky to grow outside! Plants grew well but preflowered out of 8 strains all moved outside mid June with proper light transition. Plants vegged for a month then preflowered, then finished flowering making looser buds. Still smelled amazing, literally like artificially flavored Hostess blueberry muffins. Effects are similar to other blueberry strains, uplifting and good daytime use. Average THC, guessing 17-20%

Geographic Origin: Humboldt

Story: In 2009, Humboldt Seed Co. acquired a clone called Razzle Berry and bred it with their original Purple Panty Dropper strain. It produced small black seeds that turned into an array of phenos as an F1. One of the phenotypes that came from that cross had a distinct blueberry scent. They captured that pheno in genetic preservation and back-crossed it with the parental lineage. In 2010 the now F2 seed line had taken on a consistent blueberry scent but one plant in particular expressed the most wonderful, comforting scent that they had ever experienced from Cannabis. They back-crossed her with a selected male from the lineage. While they were harvesting the plant one of their trimmers exclaimed "this smells exactly like Blueberry Muffins".
