Description for Royal Highness

A cross of two distinct populations (Royal Kush and Trainwreck) gives it vigor and ample terpenes (Myrcene and Pinol) that will knock your crown off. Greenhouse flower samples were tested and came back with high THC and some CBD (roughly 1%), making this strain a powerful medicine. Its hybrid vigor makes it live up to the Highness and the partly Sativa lineage keeps the mold away! ​

7th week Flower 🌺

By 420chicano on March 18, 2019

I am in the seventh week of flower with this RH plant running her next to a Sative Clone from DHN Sour D Lemon Kush. They both are in 7 week of flower and look So Great! The Royal highness plant Is as advertised Great buds super frosty Heavy looking. You must FIM or Top I topped and got 4 really bad ass Colas! Must tie top colas up they get heavy even for Indica plant. They look ready at 7weeks I will start flush this week . Not huge in yield but well worth the grow for people who like quality Smoke. If you wAnt big yields grow out door or grow Blue Dream.
Nice clone a growers plant

Very sensitive to cold!

By Charles on January 28, 2019

Keep this plant warm!

I have grown this strain several times now, and find that this plant is very vigorous in the vegetative stage, but growth arrests during flowering if the nighttime temps drop below the mid-50s, which limits the yield.

Standard top shelf

By John Wilkins on January 21, 2019

Pretty good bud, classic stinky piny weed, indica sleepy forsure fairly potent. nugs are large but not super dense which was good as it kept mold away but the yield was not huge but it also was not small so im not complaining as the flower it produced was top notch. The plant and buds did turn a dark purple at the last weeks but after drying and curing it turned to just a dark green which was dissapointing. Dark heart really needs to change the name as there is alot of confusion with consumers and retailers if this is the royal highness with high cbd from royal seeds or another varient.

Royal Highness Review

By Jason P on January 9, 2019

Well Im back with another review. This stain was ok, i say that bc ive grew a few now with the same set up and well with the product coming out awesome i think i would want something that maybe yielded a bit more. So far to date i had the most weight from the Purple Kush. I may want to try the purple punch next. I think the thc level mid to high 20s im sure.

Fast great buds.

By Rick Hunter on October 1, 2018

Hi fellow growers. I ran out of time and space, and had to bud these plants small and young. I was surprised at how fast they finished and the high quality of the frosty buds. Not my heaviest producers, but really great buds, and mine finished in about 7 weeks of flower time. I’ll grow these again.
