Had to bring the three girls into the garage and buy my first HPS 600watt. Got them on 12/12 and hopefully end up with something decent. They had many cool days with no hot weather or sun. SALVAGE!!!
Nice thing about autos is you can flower them in June and July during the longest days under the most intense sun. Helps make up for the short veg period. I've only done a couple this way, but starting them inside in May and putting them out as soon as the last frost has passed means even the longest running auto should be done before September, IE the frost danger zone.
