We recently bought a large polytunnel/greenhouse from Ebay,we considered it was a good buy,we paid around £45 for it and that was including the carriage.It ws easy to assemble and a much cheaper way out thatn buying another glass green house for our allotment.We have secured it much as we can and when we had the recent high winds it appeared to with stand them OK.Im wondering if there are any Mylotters that are into the Hydrophonic fruit and vegetable growing?

I have never heard of anything like this before! What is hydrophonic fruit and veg? We do not have greenhouses or things in our garden as we are not really into all that sort of thing. We are just in the process of slowly having the garden done up but I doubt I will grow any veg although I would not mind trying to grow some tomato plants.

Sorry Rose I added an H whare there shouldnt have been one!!but heres all about hydroponics
Hydroponics (from the Greek words hydro (water) and ponos (labour) is a method of growing plants using mineral nutrient solutions instead of soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, or mineral wool.
Plant physiology researchers discovered in the 19th century that plants absorb essential mineral nutrients as inorganic ions in water. In natural conditions, soil acts as a mineral nutrient reservoir but the soil itself is not essential to plant growth. When the mineral nutrients in the soil dissolve in water, plant roots are able to absorb them. When the required mineral nutrients are introduced into a plant's water supply artificially, soil is no longer required for the plant to thrive. Almost any terrestrial plant will grow with hydroponics, but some will do better than others. It is also very easy to do; the activity is often undertaken by very young children with such plants as watercress. Hydroponics is also a standard technique in biology research and teaching.
