If you grow them outdoors then sow the seeds from March – May in a good quality seed compost and cover lightly (appx 2 – 3 mm) with vermiculite or compost.

Keep the compost moist but not water logged.

Germination will take between 1 – 2 weeks at minimum 16 Deg C

Once the seedlings are large enough to handle carefully prick them out and re pot into 3″ pots.

These can be grown on until late may June and then planted either outside once all risk of frost has gone or kept in a cool greenhouse.

Or you can grow them indoors all year round using hydroponics & specialised lights.

    I would give this a higher score if I could as it is one of the most important plants you can grow at home. Adding this type of fresh tomato to your recipes makes a huge difference. The ‘secret’ is to grow it using hydroponics & extra light – so you can crop it all year round
