TH Seeds

T.H. Seeds is a Amsterdam-born cannabis seed bank founded in 1993 — one of the first to put American genetics into European hands. We've stocked their gear since the early days and carry the full working catalogue: 30 feminised photoperiods, autoflowers, the S.A.G.E. family, the HOG line, and the newer dessert-terp hybrids.

Buy T.H. Seeds Cannabis Seeds — The Full Range

T.H. Seeds cannabis seeds are feminised and autoflowering genetics bred by an Amsterdam-based seed bank that's been running since 1993. Five Cannabis Cups, a catalogue that spans old-school Haze hybrids to modern gas-and-candy crosses, and genetics you won't find rebranded elsewhere. If you want a single shortcut: S.A.G.E. and MK-Ultra are the two strains that built their reputation, and both still sell.

Choosing by flowering time and photoperiod vs. auto is simpler than choosing by sativa/indica percentages. If you're growing in a tent with a 12/12 switch and want maximum yield, go photoperiod. If you're growing in a cupboard with one light on a 18/6 schedule and want to forget about it for two months, order an auto.

Who T.H. Seeds Is, And Why It Matters

Adam and a small crew started T.H. Seeds — Thai, Hawaiian, Sativa — in Amsterdam in 1993, bringing genetics back from California when most European breeders were still working with local landraces. S.A.G.E. (Sativa Afghani Genetic Equilibrium) won five cups. MK-Ultra took two. The HOG line — Tennessee HOG crossed with everything from Critical Mass to Northern Lights — is their indica workhorse range. The newer material, Gelato Cake and Mont Blanc and Banana Candy Krush, reflects where modern cannabis breeding has gone: dessert terps, candy-gas flavour, purple phenos.

We've sold these seeds since Azarius opened its doors in 1999. The older strains still deliver — S.A.G.E. is 20%+ THC with a sandalwood aroma that genuinely doesn't exist elsewhere — and the newer drops hold up against anything the US scene is shipping.

How to Choose Your T.H. Seeds Strain

Buying your first pack? Start with an autoflower. Auto Bubblegum is the most forgiving in the range — sweet, compact, ready in 70–80 days from germination, no light-schedule changes to track. Auto Critical HOG is the one to order if you want bigger yields but still want auto simplicity.

Second or third grow? Step up to a photoperiod. Critical HOG flowers in 55 days, which is about as fast as photoperiod cannabis gets, and the plant is forgiving. MK-Ultra stays compact at 100–120cm, which matters if you're in a 80x80 or 100x100 tent. For flavour over yield, Gelato Cake or Mont Blanc.

Experienced grower chasing trophy buds? S.A.G.E., Kushage, Sage 'N Sour, or the Runtzy/Beasty/Mona Lisa end of the catalogue. These reward attention — feeding schedules, training, defoliation — with the kind of buds that make the effort worth it.

Honest one: if you're growing outdoors in a Northern European summer, skip the long-flowering Haze-heavy strains (S.A.G.E., Sage 'N Sour). The autumn will catch up to you before they finish. Pick an auto or a fast indica instead.

Frequently Asked Questions

Where can I buy T.H. Seeds online?

You can order T.H. Seeds direct from Azarius — we've stocked them since 1999 and ship across the EU. The full catalogue is on this page: feminised, autoflower, and the 30th Anniversary collector's box.

What's the best T.H. Seeds strain for beginners?

Auto Bubblegum or Auto Critical HOG. Both are autoflowers, so you don't need to switch light schedules — plant them, feed them, harvest in 65–80 days. Auto Bubblegum is sweeter and more compact; Auto Critical HOG yields harder.

What is T.H. Seeds known for?

S.A.G.E. and MK-Ultra — both Cannabis Cup winners, both still in the catalogue 20+ years on. T.H. Seeds was one of the first Amsterdam seed banks to bring California genetics into Europe, and the S.A.G.E. lineage (Kushage, Sage 'N Sour) is genuinely unique to them.

Are T.H. Seeds feminised?

The current catalogue is entirely feminised, including the autoflowers. Every seed you get from us will produce a female plant, so you don't need to sex them or cull males.

How many T.H. Seeds strains do you stock?

We carry 30 T.H. Seeds strains at Azarius — from the original S.A.G.E. and MK-Ultra to the newer dessert and gas hybrids like Gelato Cake, Pure Runtzy, and Beasty. Pack sizes are 3, 5, or 6 seeds depending on the strain.
