Hydroponics use outside

Hello I was wondering if anyone could give me a bit of advice.We have our grow tent set up we are now ordering a Hydroponic system (between NFT gullie or Wilma) but its hot in the UK right now is there anyway to put the plant out side while it is in veg and then some how transport it back into the hydroponic system. ( No better light source than the sun)
