Im not opposed to requesting a cup bottom pic.
And you can also tell if the roots were really in or out of the cup. If they stay in. You will see a root bound root ball. Wrapping around cup.
If cut roots. We will see roots go to cup and cut off instead of curl and wrap.
But i do understand what you mean. Which is also why its a beauty contest and not a size contest. I feel you though some of these dwc set ups can be a bit intimidating.
You know that I would not have a problem taking pics of bottom for my weekly/biweekly updates. I set this hydro up in less than 1/2 hour with stuff I had. Intimidating? Yup..but I feel that if people wanted the biggest plant that they would have chose hydro. Some people chose not to because of possible combination of intimidation, increased care, or lack of space/gear. Which is absolutely their choice. I commend every in any type of solo cup grow...because regardless..its a bitch.
