I’ve finally made some time for myself to share my masterpiece Its room with 4 pcs of 1000w HPS… Time to compare results with old 600W room…
To stay ahead of questions - that red thing hung from ceiling is sulfur burner. It is guaranteed tool to kill all spider mites, with which we had problems.
It works very well, you just need to put it on timer, fire it in the room with stopped ventilation. Let it smoke for 20 minutes and then vent smoke out. It is very poisonous for all living creatures, and you must leave the area till it is ventilated out.
