How close can I put my 400W HPS to the plant if it has a cooltube on it
nah i dont have one with a wire, but thats a good idea and ill probably get one. thanks for the infoYou should be able to safely put the light about 20" from the tops of the plants. Do you have a thermometer/hygrometer with a remote wire or wireless remote for the outside temp? Mine has the remote wire so what I do is run the remote wire down the chain hanging my lights and let the remote dangle about 6" above my plant tops. That gives me an accurate temp reading directly below my lights and allows me to ensure that the temp at my canopy never goes above 82F.
2 or 3 inches just above the plant? dam thats close , u sure?I meant 2 or3 inches and 3x3x7 feet.
i figured u were right, when i seen the other guy say 2-3 i was like, ummmmmm..........Putting any HID lamp 2"-3" from the tops of your plants will burn the shit out of them, regardless of whether it's a cool-tube or not. I'd say you want that lamp no closer than 16"-18" from the canopy. It would be a safe plan to start with it at 24" from the tops and gradually lower it, little by little, until you find the threshold.
