It’s morning in America, and we’re chugging Orangeade. Grab some sweet, citrusy, and grape-tinged THC power to wake and bake through weekend chores with this cultivar.

Symbiotic Genetics of California crossed Tangie and Purple Punch to make this hit hybrid. Strain traffic to Orangeade is up 14% month over month, closely pacing its cousin Mimosa (up 13%); both are perfect for that first girls’ weekend away.

If you like Do-Si-Dos, keep an eye out for Whoa-Si-Whoa. Bred by Cannarado of Colorado and selected by Top-Shelf Cultivation in California, Whoa-Si-Whoa earned a 2019 Cannabis Cup. Expect a big OG Kush bite and funk from this amped-up Dosi. Great for appreciating the special effects in the new Mortal Kombat. Finish him!

Save up for this sweet-savory splurge that’ll put you in da couch. Symbiotic Genetics of California crossed GMO to Purple Punch for this powerful meaty-onion and fruit combo perfected by growers LitHouse. Modified Grapes works great as a digestif after that first outdoor dining experience of 2021.

New on dispensary shelves—Diablo Wind by Houseplant, CA

Actor Seth Rogen’s California launch of Houseplant defied “celebrity weed” critics to deliver big, terpy, awesome, top-shelf indoor nugs. Now in 17 inviting dispensaries, all three Houseplant strains pass muster.

Diablo Wind offers a bright, energetic counterpoint to all the Cookies out there. Diablo Wind is Jack Herer x G13 Haze. It’s similar to XJ-13, and that stuff is great for daytime activities—like a pottery class!

Rocketing up the charts—Grape Octane by Alibi Cannabis, OR

Woman-owned Alibi Cannabis of Clackamas, Oregon keeps delivering indoor quality to discerning smokers in the Beaver State. Their whole lineup is legit, but Cannarado Genetics’ cross of High Octane OG and Grape Pie is a guaranteed winner.

The gassy, diesel smell hints at grape and fruit and pairs well with the final season of the Kardashians, or a trance-like Minecraft marathon.

The Quest for perfect California indoor is over at Source Cannabis. Source’s flagship strain is a variety of Original Glue (aka GG4; a cross of Chem Sister, Sour Dub, and Chocolate Diesel) bred by GG Strains. Buttery lemon and sharp pine aroma give this potent strain a lift that pairs well with chill hobbies like spring gardening, or Zoom poker.

In lab tests, GG4 is rich in astringent pinene aroma, supported by dank myrcene and caryophyllene.

Ballin’ on a budget—Lemon Cane YOLO, by Archive CA

This bargain outdoor grown flower from Yolo County, CA keeps giving us life. Archive Seeds of Oregon/California crossed a Lemon Peel to a Do-Si-Dos for gobs of thick lemon syrup flavor with a mega-bodied fuel finish. The outdoor product (dubbed “YOLO”) rivals indoor for value, terps, and effects.

It’s great for numbing the mind and blasting through 1,000 unread emails. Better yet—delete all, and set your Vacation Reply to “YOLO.”

High Note: Patty Cake rosin, Kalya Extracts/Zenganic delivery

Prepare for a world-class extract that stones you to your core. Oakland-based Kalya extracts took 1st, 4th, and 8th place in solventless extracts in The Emerald Cup this April, winning with Patty Cake, a cross of Wedding Cake, and Gelato #33 grown by Landhammer Farms. Landhammer gently froze freshly harvested buds, then Kalya ice water-hashed out the plant’s trichomes, and cold-squeezed and filtered the pure reson.

The result looks like a sci-fi metamaterial and smells like the extracted soul of the flower: rich, deep, and sweet with GSC terps. Keep this expensive hash sealed and frozen below 32 degrees, and make sure to wait 15 minutes for the translucent Patty to come to room temperature before opening and dabbing at low temps. Then silently meditate in the woods for hours. Delivered by Zenganic delivery in Oakland.
