They currently have 2 to 4 true leaves. Would 15 module trays provide enough depth for a further 5-6 weeks of growth or would 8cm pots be a better option? 7th April 2016 at 6:10 am #33824 charlesModerator I am unsure Rhys, suspect that 8cm would be enough and in your urban location it should be frost free within 3-4 weeks. 7th April 2016 at 7:42 am #33826 RhysParticipant OK, I’ll go with 8cm pots then. Funnily enough, we’ve not had a frost for about a month, but enough lows of 3-4C and days no higher than 11C mean that growth hasn’t been too spectacular yet. And nothing apart from radish would germinate in the soil before the end of March. Author Posts Viewing 3 posts - 1 through 3 (of 3 total) You must be logged in to reply to this topic.
