Dark Light

When you buy cannabis seeds, consistency matters. Nothing is more frustrating than planting the same strain only to see different results each time. Inconsistent genetics can mean wasted time, money, and effort.

CG Australia takes the guesswork out of growing. Our seeds are carefully selected and tested to ensure stable genetics, giving you reliable results harvest after harvest. Whether you’re chasing high yields, rich terpene profiles, or specific effects, you’ll know exactly what to expect with each grow.

With CG Australia, consistency isn’t just a promise — it’s the foundation of every seed we sell.

Multi Pack 10 AUTO Sativa Feminized Seeds
Over 90% germination across a variety pack is pretty good I reckon. Typical temperamental Autos, I think I stick to Fems

Whilst I am a fan of the site and service and I will continue to use this site, Here is my last experience. In this instance I actually recieved the wrong order. Got 2 of the same type seeds (AK47, one auto and the other fem) I actually had ordered AK47 fem and white widow Auto. Made contact but no plan to rectifie this has been made except 30% off my next order.

Have bought for myself and friends through this site for two years now. We're all very happy with the product. Yet to have a seed fail to germinate. Delivery is discreet and well packaged. Yield was amazing on the Girl Guide Biscuit and Purple Haze, trying out White Widow and Guerilla Glue this year. Will definitely use this service again. Have paid with regular payments and crypto, the latter being seamless. Thank you!
