Jesus H Christ
I wasnt trying to start an argument over whether drainage is necessary... you wanna run that way be my guest.
I personally know for a fact your plant would be healthier with proper drainage. I dont even need to see a pic or have a lab coat to tell yiu this because when I started I didnt put drainage in the containers and used clear. Shocker I know, you can grow a plant this way but you will have a much happier and healthier plant once you elmiminate light to the root zone and give it drainage so you can get runoff.
So do what you will, shouldnt have prob even said anything in the first place. Just thought I would give a little advice with a friendly poke in it...
And captain morgan, I get where you are coming from in the fairness angle but do you think a stray root or two is really gonna be the fdifference maker? I mean unless you are just letting the cup sit in water they dry up outside the cup, I would be more worried about the water boys getting an edge from that.
