      I kinda thought the same, about this being a hot summer  Ive tried before up here, without any real success, but a mate grew out some plants in a polytunnel, which were frickin huge. They succumbed to rot tho, when the weather went pear shaped in august a couple of years back. Ive not tried autos tho, so hopefully they will fare a bit better,  I will give it another try, would really like to do a greenhouse adventure, but cant , due to ex-copper neighbour and nosey bastards. I might well be wasting my time, but if you don't try, you never know eh?

      Forget q anon, Nessie is making a comeback   https://www.theguardian.com/uk-news/2018/may/23/scientists-dna-hunt-loch-ness-monster-scotland     Theres actually some interesting science in there, using PCR to amplify all DNA found in the lake, it give amazing data sets on biodiversity.   I'm hoping to be involved in something similar this summer assessing the fungal community of an ancient woodland and a reclaimed quarry site.

      I get mixed information on the CMH 315 being as powerful as a 600w HPS...the theory being the CMH has 90% usable light spectrum and the HPS 50% odd and a lot of heat. (far red spectrum) The CMH get better taste reviews but people are reporting more stretch with these bulbs.  You can see your girls better under CMH as its a more natural light making spotting problems far easier.   I must admit I'm tempted by a 630 CMH to replace my 600HPS but would still keep the ballast for the MH.....Im waiting, reading that thread and waiting to pounce lol.   (would mean a new reflector as well)
