How this comparison works
THCA is the acid form of THC. Heat removes a carboxyl group and converts it to THC. The mass conversion factor is 0.877. A flower that tests 25% THCA yields about 21.9% total THC after decarboxylation. Labs report both numbers. Ask for the COA before you buy.
This ranking uses four inputs: reported THCA on a batch COA, terpene profile, trim quality, and price per gram. THC numbers move with each harvest. One COA covers one batch.
Top pick: Gorilla Glue #4
Vendor COAs for this cut land between 22% and 28% THCA. Caryophyllene, limonene, and myrcene dominate the terpene panel. Buds are dense and resin heavy. Trim is tight on most lots, so stem weight stays low. Price per gram sits in the middle of the range. The COA is the reason it ranks first: labs report THCA and delta-9 THC on the same sheet, and the total THC math is easy to check.

Option 2: Blue Dream
Reported THCA runs 17% to 22%. Pinene and myrcene lead the panel. Buds are larger and looser than Gorilla Glue #4. Stems are thin, so usable flower per gram is high. Best pick if you want volume over peak THCA.

Option 3: Jack Herer
Reported THCA runs 18% to 23%. Terpinolene and pinene dominate. The nose is sharp and pine forward. Bud structure is less uniform, and smalls show up in some lots. Check the grade line on the listing.
Option 4: Wedding Cake
Reported THCA runs 20% to 26%. Caryophyllene and limonene lead. Buds are tight and trichome coverage is heavy. Price per gram runs higher than the other three. Good pick when density and bag appeal matter more than cost.

What to check on the COA
- THCA percent and delta-9 THC percent, both on dry weight.
- Total THC, calculated as THCA times 0.877 plus delta-9 THC.
- Harvest date. Terpenes fade after a few months.
- Moisture content. 10% to 12% is workable.
- Microbial and mold panel. A pass should be stated, not implied.
Legal note
Federal hemp law caps delta-9 THC at 0.3% on dry weight. THCA has no federal cap under that rule, so high THCA flower sells as hemp in some states. State rules differ. Confirm your state allows the sale before you order. Store flower in a sealed jar away from light and heat.
