Hydroponics on rockwool , a step by step guide that goes through all the aspects you have to deal with once you start growing on rockwool indoors. The author motivates the products of his pen: "The frustration of trying to create a simple, effective, indoor growing environment with the currently available books, videos and conflicting verbal advice drove me to writing. This may be a decision I will live to regret. Drugs or drink may well have been a better solution". Fortunately, he has not had any regrets and he has also written 'Growing on Coconut' as well as 'Simply soil'.

With many colour photos and diagrams.
