Has anyone else messed with this? Any tips or successes please share. Those are 2 Empress of India, 1 Jewel mix, 1 Alaska mix for anyone wondering. Lacinato kale bottom right in my other unit. Desert rose in the small pot on the floor. Microgreens tray covered on the left. I’m think about putting another tub underneath on that shelf with all the hydroponics equipment. Creating my first double stack vertical DIY DWC setup for a total of 8 tropaeolum with side lighting. Ideally they’ll fall down the sides, we’ll see.
Well that might be the issue then, because I’m reading these plants actually thrive in nutrient deficient soil for the most part unless flowering.
If that’s the case, just hold back on refreshing whatever you have in there now on your usual schedule. If they start getting new growth when what you’ve added has been used up, just add 1/4 of whatever you’ve been adding at the next refresh after letting it lapse.
So skip a refresh, see how they do, then wait a full refresh period before adding 1/4 the amount you normally add.
