They are developing nicely. I have one in 7l plastic pot, 11 l plastic pot and one in 11l fabric. The one in fabric pot I by far the biggest yet. We will see how they'll end up.
@Grower202085, I mix ro with tap depending on the season to make 0.4 ec water. In summer it’s ok straight from the tap but in winter it’s sometimes 0.8 from the tap where I live.
