Outdoor bagseed grow

Enochian I have made this diary as a bit of a goof for a mate of mine. He gave me around 50 seeds he had saved over the years from the weed he had bought. 12 out of 50 popped and as I don't know what strain/genetics/sex these will turn out to be and as I have a shortage of space at the moment, I bought a cheap PVC green house and have them outside. They seem to faring better than I expected although the day I put them out was a dry and warm day every day since has been a downpour and nearly collapsed said greenhouse under weight of gathered water. Had to prop a pole up inside to form an apex for the roof to allow rain to runoff at stupid o'clock in the morning. August and September seem to be better weather up here in the mountains so hopefully they can manage to survive till then. Not expecting much if anything all of which will go to the seed donor, (urghh...that just doesn't sound right). I am just curious if an outdoor grow here in the UK can be achieved and if so, what results can be expected. Very high humidity here at present which will suit the seedlings, I'm sure.
