So I have tried to engage people on here before regarding solo cup growing, and I am new to this, some would even call me a virgin, however I am very curious about it and willing to ask again. Is it the space saving potential and number of plants that you can pump out that is appealing? I think it is very cool, I am just trying to understand the reasoning behind it. Also are you having to hit it with nutes every watering? Can you share with me a link so I might investigate this more?
