sorry about that mate.need more details before answering this, such as which form of hydro are you set up with, what was the root mass like on the rockwool, etc etc etc
you cant just say I stuck a plant in a pot, will it grow? details are essential
could you explain, "accurate measurement of spacing between plants"on an ebb n flow table, yes both options are suffice. Only the net pot method will allow you to get a more accurate measurement of spacing between plants
if you have a 6inch net pot and a plant is in the middle of that one, and you have another 6inch net pot and a plant in the middle of that net pot as well, then you have a plant spacing of ~6inches apart...these measurement would be best used in a Screen of Green (SoG) method to get accurate spacing to optimize getting the appropriate number of plants on one table under the one lightcould you explain, "accurate measurement of spacing between plants"
