Re nutrients, can you please recommend/advise is there any better nutrients than Canna? In our case we are using Canna Hydro (for hard water) for medium which contains clay pebbles and 6inch rockwool cube in the middle. 16l pots and autopot system.
If it’s an organic liquid feed and only lasts for this period of time then it would not be suitable but can be added into the tray by turning off the reservoir….. following day pour in tray leave for 30 mins then top up tray ….. following day turn reservoir tap back on…. repeat every 5-7 days
