Ok, cheers. This sounds like the way forward. Do you mean water daily and get a run off? As long as the roots are established. Last question, would you identify an established root system once you transplant the root cube, with roots visible coming out the bottom, into say a 1 litre pot. Or do you mean an established root system within the 1 litre pot. The reason I ask is I’ve never known it to be ok to water so heavily when the seed is so young, say a couple of inch. Cheers
