After growing with HPS years ago, then only growing outdoor for a loooong time, I’ve come back to indoor and LED also. My grow is only a little 60 x 90 x 180cm set up but it amazes me how different LED was compared to HPS. Prepare for your plants to need a lot more cal-mag.. Hope the learning curve is small and less bendy than mine
Didn't know about ekstra Mg usage. Good to know.
Sort of makes sence to me.
In my coral-farmer hobby I changed from HID to LEDs some 10 years ago, and we had to figure everything out ourself.
Change to LED gave us more chlorophyll, and a demand of pigments to limit photosynthesis. More usage of N, Mg and so on for chlorophyll and Iodine (for pigment).
Given Mg's role in chlorophyll, I think I understand why they would need more Mg..
Thanks for the advice, will do
