On both plants, autoflowers, I did mixed, inferior lighting - some sun (mostly through the window) and a cheap, small light. Only when I was well into flowering on my second plant, did I get a light that would be considered mostly decent. So, that being said, expectedly I had what is considered lower yields, which is totally on me and my cheap arse lighting. The product is potent, though, and does the job quite nicely.
I expect higher yields going forward since I’ll be using only one light source and one that’s better.
When others on here say to get good lighting, then listen! Many recommend HLG, and yet others have done well with some of the better brands on Amazon and such. Search and poke around on this forum for many lighting topics. I see that the HLG 100 was recommended above, and I’ve seen many others love HLG’s 135 that is about $50 more. Others have searched on google for an HLG discount code.
