I have decided not to cut off anything.
Because I read somewhere that during flowering the leaves makes sugars during 'daytime' which the convert in the good stuff 'at night'
Photo period down to 13/11 now. As of tomorrow 12/12 straight.
These photo's I made today to show progress :

crowded box

favorite plant

favorite from above

least favorite plant but it does show me a V-sign.
crystals all over the place
too bad I had to use a flash while making the photo.
Tomorrow I will do one in daylight so the contrast is better.
