Well I've expanded from my usual 3 under one light to 36 pots under 6 lights.
Absolutely massive compared to what I'm used to.
Also switched from biobizz to canna for the 1st time so I'm completely out of my comfort zone.
Doing OK though if I do say so myself. Only issue I've had is temps being a bit low for a few days during lights off. I've gone from growing in a house with central heating to growing in a large shed so it was a learning curve.
Got it sorted now with 2 radiators controlled by a little computer thingy Bob. Plants did look limp and started to yellow a fraction but have bounced back nicely.
I'm finding the canna terra soil and nutes OK. A lot more complicated than biobizz. I'm having to ph adjust which I never did with biobizz and the pH for canna terra Pro is 5.8-6.2 not 6.5 like other soils.
I found this out a week into grow lol.
With all these little things I've been learning on the go I'm amazed how well the plants are doing.
