Pacific Northwest outdoor grow question

[Aviendha]

So I have a nice space for a few plants in my backyard. I will be bringing in some soil before planting as well. Before I plant what temperatures should I make sure we are above at night? How far apart should they be planted? Secrecy is not an issue. Thanks!

This is a little snippet from RQS. -15 means below 15C, not -15C.

Should temperatures fall below 15°C, cannabis plants are effectively in the danger zone. The risk posed by pathogens and pests increases exponentially. Growth will cease and then leaves will discolour if the cold does not abate.

Varies some on the Strain as Sativa or dominant like it a little warmer than Indica or dominant seem to. I have gone sometime in May both times, I waited until it quits getting down into the mid 40s at night, though mother nature hard to predict when she will throw a frost at you from out of nowhere. I have had two in my little garden spot, probably 18-20" apart.
