This will be my 3rd grow and all is going well by now I germinate seeds in pure water and after 2 days all 10 of them germinated Yes, they are feminised too. So i have 150w hps bulb with remote ballast, 3 120mm fans going out (one is connected to the light hood and its sucking hot air directly from the source and out). Another 120mm fan is in front of the bulb just to run bulb at lowest temperatures possible. 80mm is for sucking fresh air into the box and two 220mm are just for mixing air in the box. For the medium i have chosen soil in 10x 2.5L pots which all are now filled with soil and just germinated seeds in it . Temperature si allright, air flow too So now i just have to wait and grow I will be back in couple of weeks to report progress of lemon skunk (hope its gonna finish defore december so i am gonna have very nice christmas and hollidays And oh...My plan is to get at least 0,7g/W And maybe i will add two 20w cfl bulbs for flowering just to have as much light possible and to cover some not-so-bright spaces in the box
