Am I right to understand that this SunSeed, and thereffore your GridSeed (for instance) would have to be in direct sunlight for this to be effective?
That's right, put it under direct sunlight.
Can you build an setup for 10 gridseeds, i want to know what i need to get them working.
Then make an video and pictures of it and show us hashing. If you can do that.
Then you will get an Big Pluss!
