i have had to put this on the back burner for a while due to it being winter and as i am attempting to do this from as many recycled and salvaged products as possible, not many heat lamps lying around for germination/sapling growth :( may splash out and buy one but the whole unit will be housed in my bedroom and heat lamps are bright, 16-18 hours of that while tring to sleep.....not good. stay tuned.....
Usually people are willing to help or give advice, so maybe if you outline the steps of the project and the bits you need help with, people will chip in.
