I'll try to answer as much as I can.

First off, A hydroponic grow as a first grow? Anything is possible...NEVER doubt yourself :thumbsup:. But it is going to be hard work and you may run into problems here and there.
As for asking about yield, I have yet to see someone answer a question about yield. It really depends on your grow environment, equipment, problems you run into or not, etc so it's hard to say... But I'd like to guess at LEASSTTT an ounce :stoned:

And Listen to Lynhal he is awesome.
