My primary space for flowering is 2.75 x 2.75 x 7 ft. The room is 136 cubic ft. total. Should I get a 270W to minimize heat issues or go for the 430W? I would like to setup with out air-cooling the light. Will 270W produce nice results comparable to 400 or 430W?
If you can keep the area below 80fh when the lamp is on for 12 or 24 hours,then go for the most wattage that you can manage.more watts can only increase the harvest if you can control the temps(78 max)which can be done with an efficient exhaust&intake air system....bonbon
