As these are not Dinafem strains I know very little on this strain but for close to 4 weeks if autos you shoukd/will be seeing some pretty flowers soon.
I had to re read your post as I thought 5000k was 5000w then I realised thus was lumens and not wattage. I do think 5000k lumens is a little low to get any significant growth from the plants but I could be wrong.
Can I ask is this about 125w?
All the best
Mark.
