hello agen - my Northrn Lights plant is doing lovely. It's 110cm tall, and quite bushy. Just started 12 / 12 lighting 7 days ago, and wee flowers starting to form. Anyway, wot i would like to know is, how much foliage / fan leaves can i remove to aid light penetration, without compromising plant's growth / health? I'm talking about big, single fan leaves, not the smaller ones beside the flowering heads. Hope someone can help. Cheers, Guv'nor.
