I don't normally write bad reviews but I am making an exception because I feel ripped off. There is nothing here that can't be gained for free on the instructibles web site. Get google and save your money for something more worthwhile.

I liked it, good buy has some good do it yourself hydroponics if your looking for a cheaper way then buying it at the store. Step-by-step process laid out clear and easy to do. I recommend this book to people who can work a saw and hammer and have so patients to make the system for you for a fare price.

This is a great set of cheap DIY hydroponics systems. Don't want to spend $150 just to try it on eight plants? Get this ebook and head to the hardware store and kill an afternoon gardening. There are similar guides online, but this is a well-curated guide without anybody trying to sell you something. Plus, there are high-quality pics included in these guides. If you're an instructables pro member, you'd get these guides for $2/month. This guide is cheaper than subscribing, has better pics than the used book store offerings, and is way cheaper (and less intimidating) than making a trip to the hydro store. Worth it.
