That makes sense. I figured id wait till they need watered daily before I hook up the system. Am I supposed to get runoff every feed or just the last one? I see alot of people feeding 6x a day
i feed like 12times / day at the moment, you need to understand how crop steering works first, if I had to explain what to do it would be something like this:
-feed many times per day start at 2hours after lights on and stop at 2 hours untill lights off.
-you want to feed many times to re up the oxygen levels in the rootzone.
-if you want to get a higher media ec, dont water to runoff and make sure you get decent dryback while not watering (night)
if you want to lower the media ec, you need runoff to do that. if you want to keep media ec the same, just a bit of runoff during the last feed should do the trick) no need for thease 10-20% runoffs if you water more than 3 times a day.
-different growth stages you will need different amounts of dryback/runoff/upkeep but generally during the "upkeep" feeds that are there just to replenish the oxygen and media water content you'd like to be around 90% saturation of the media even if you would try to stack the media ec you still need to have proper levels of water and oxygen in the root zone. hope this helps!
