For many who flick through the TGA catalogue, the place to stop is right at the beginning with the Apollo 13.

A fantastic all-rounder and great for those who have just binned their learner plates.

This is a super-charged grower with a beautiful plumage and an amazing array of flavours. It is highly resinous and well-loved by growers keen on making thick, potent hash.

It's Go Time! This baby is a lively and refreshing sativa-dominant jewel in the TGA crown, with well-loved invigorating and euphoric effects. The plant provides a unique mix of analgesic, energising and aphrodisiac qualities and the extraordinary flavour profile takes in lemon, fuel and stinky cheese. It is a truly remarkable strain and one that will not be forgotten in a hurry.

A grape flavour in a marijuana plant is often a sign of high-quality genetics and the Grape Inferno is no exception. The pungency of the aroma is matched only by the potency of the marble buds and it is easy to burn through more than expected on account of the delicious taste. This is a refreshingly different strain and if customer feedback is anything to go by, one well worth a dabble.

Purple Urkle meets Jack the Ripper to create a beautiful hybrid plant that’s renowned for its strong, fruity aroma and gorgeous magenta colouring. When smoked, it creates a pleasant, narcotic body and head high that can lead to couchlock in higher doses.
