Gigantor Seedless THCV
Gigantor Seedless – Triploid Feminized THCV Seeds
Lineage: HO40 × Auto Durban THCV
Type: Type I, Varin Rich
Gigantor Seedless is a triploid, feminized THCV seed variety and one of the most advanced backcrosses available on the cannabis seed market. Derived from the original diploid HO40 THCV germplasm and hybridized with the Auto Durban THCV line, this variety delivers exceptional yield potential, dense resin production, and THCV-dominant flowers.
By converting the HO40 parent to a tetraploid, we unlocked the power of triploid cannabis seeds, allowing for larger, more vigorous plants with improved cannabinoid content while reducing flowering time through hybrid vigor. Gigantor Seedless is perfect for varin extraction or producing show-stopping, high-THCV plants.

About Triploid Cannabis Seeds
-
What are triploids? Triploids have three sets of chromosomes (4N + 2N = 3N) instead of the usual two in diploids. They are common in agriculture, including bananas, seedless grapes, watermelons, and citrus.
-
Why triploids? Triploids are largely sterile, produce denser flowers, higher yields, and stronger aromas, and are more frost-covered than diploids.
-
How triploids are made: One parent is converted to tetraploid using colchicine and crossed with a diploid to produce vigorous, high-quality triploid seeds.
-
Seedless but not GMO: Triploid seeds are certified organic and naturally bred. Heavy pollination may occasionally produce some seeds.
Gigantor Seedless triploid THCV seeds are ideal for growers seeking high-THCV, feminized, and high-yield cannabis plants for premium smokeable flower or extraction.

Well-grown crops with good field conditions and accurate testing can yield 15-30% total cannabinoids variety dependent.
Growing technique, nutrient regime, sampling protocol, drying method, post-harvest handling, and laboratory accuracy all factor into total cannabinoid content on a crop-wide average.
Ratios refer to CBD, CBG, or CBDV/CBD percentages to total THC.
These COA's were taken from plants 30 days pre-harvest as required by the US Department of Agriculture, and are not an accurate representation of finished flower cannabinoid content.
For finished flower results we suggest seeking out results from other farmers who have grown our varieties. We cannot guarantee finished flower results, so we do not post them.
All seeds are feminized seeds.
A minimum of 10% extra seed is added to every order.
All seeds contain less than 0.3% total THC. Understand your local laws and ordinances before planting.
