I have just purchased an Amazon twin 32 hole and have just put seedlings in today x32, I will try to put a pictorial log on here for you to follow if you like. As for the quality and build + parts etc......well.....perhaps I am just an anal f***er but I felt it could have been made better. All the component pieces were vacuum formed and had a slightly shoddy finish to them, the shop I bought it from sent the wrong lids so had to replace them, when I got the new ones it seemed like they had cut the holes themselves as they were not placed all that precise and I had to tether the edges myself.
But once assembled and put to run for a few days to get the water PH and temps in the new tent right it seemed to be going great guns. What is nice is that I think I can get away with using less water in the resevoir....80L instead of 120L which is a 30% saving of the nutrients. Yield should not be affected by this.
The Amazon seems to also be the most cost effective Aeroponics kit out there from what I've seen and considering it is one of Nutriculture's products and they are British, it is piece of mind for spares etc.
In fact.....unless it all goes pear shaped I shall be purchasing another twin 32 next month so that I will have a veg room and then it's a straight shift into the flowering room. Do bare in mind though what sort of plants you intend to grow as this will greatly affect how many holes you choose, I felt that more was better as you could just plug the unused ones with foam clone plugs.
I hope this helps you, it took me 2 months of scouring the net for an Aeroponics system that was of best value and price, for me it was the Amazon....but that's just my opinion though! LOL.
Peace.
