postmandave Reviewed by postmandave on . BlaZin's 1st Grow What up everyone! This is BlaZinROC's 1st grow. We have a 3x3x5 growbox. Using a 400 watt MH for the Veg. and plan on switching to a HPS for flowering. We are currently on day 26 and using bagsseed. The one's in the solo cups are only on day 5 and are endless sky strain. It stays a steady 74 - 80 degrees during the day. We pruned 3 yesterday and hopefully everything works out. Let us know what you think. Peace!:thumbsup: Rating: 5
