chasv77answered grow question 5 years ago In my opinion, if you started her indoors then moved outdoors, you should phase in that direct sunlight, as it has UV/IR light, that may not have been in your grow area.
10C = 50F, which will stop the plant from growing, but wont kill it. I know, it happened to me with Chemdawg. It took me 2 weeks, to get her going again, after I fixed the temp issue. The starting point for healthy LOWs I have found, is dependent on strain, but yes 17-18 C is about the lowest you want to go. If it is already in the ground, you may have to cover the plant at night, until your outdoor temps get up to speed.
