Why I'm different
A different breed of education
Mistake-first teaching
Every lesson opens with the mistake most growers make — then shows you exactly why it happens, and what to do instead.
Built from the research
No bro-science, no forum myths. Each module is grounded in peer-reviewed studies, cited at the foot of the page.
Irish & independent
Made in Dublin, funded by no one — this is my gig, not a brand's. Full disclosure: I work for Dublin Indoor Gardening, so yes, I take a percentage on the affiliate and seed links here. But nothing gets a link unless I personally back it and run it in my own tent.
