As a fan of mini greenhouses, this seemed like the ideal answer for growing my tomatoes. It was just the right shape for a growbag and was entirely sealed - no chance of any slugs or insects getting in. This seems like a great idea and in theory with the grow bag holding it down you would think that this is a fairly solid little green house. Sadly the plastic cover is worryingly thin. The support poles are also far less sturdy than mini greenhouses I have purchased from DIY stores. I placed my seedlings in the growhouse within the growbag and after one slightly windy day, the how lot toppled over, tipping the growbag over and flattening my seedlings. The support poles buckled and the plastic ripped. So...I now have a pile of metal and torn plastic in my shed! I will now be buying another of my trusty mini greenhouses from somewhere and just keeping an eye out for the slugs etc. Shame, was a fab idea.
