Sorry for the late start...
I've recently arranged the plants according to size. 4 small 4 tall. Both for lights and scrogging.
Using growth technology coco grow and cal mag according to the bottles, and a reservoir.
I know how much feed is going in according to how long I leave the pump on, I don't know exactly how much it is. Always 3-5 litres of drain.
@Secretflower, nice one!
They're very sticky too!
One of them I've been flushing the last couple of days (I'm back from the future) so I'll yoink her out tomorrow and put her in the dark for a couple of days then see what we got!
