  2. Had a thought earlier today,... like you do, I'm in a pixie tent and sort on space so I was thinking get a small 1ft tube heater, one of them thin ones, stick it inside an 18" length of 4" waste pipe and connect inline to passive air intake about 50cm from tent intake opening, for the winter. I turn down exhaust fan at night but last two nights mins were and 66/18.8 and 64/17.7 they still sucked up half a litre while lights off for 6 hours so I'm guessing by uptake they wern't dormant in that period......... maybe I better start checkin bucket temp. Going 12/12 this week and will have light off in the day but it's getting winter out there and there will be more cold to come. Wondering whether it would be effective and whether anyones done this b4, I could close off the end of passive intake as well a bit so the air doesn't rush past the tube/waste pipe bit as fast. Oh the tents in a cupboard only about 18" from a water tank so it's never gunna freeze right out in there, the passive is the only way it will cool cos of fresh air.
  3. Heya all, Just wondering if someone could chime in about their experience with a tube heater in a DR60 or hydrolab 60 or a 60x60x140 grow space. Dilemma: lights off, temperatures are reaching a low of 18C at the moment. I'm on a 20/4 light schedule - the tent is in a cupboard, passive circulation using a 100mm RVK when lights are off with a 120mm pc fan just below the lights. When lights are on, the ambient air is fine at canopy 25-26C and ~22-24 ground, helped further by a 100mm inline intake and two 6" fans which all come on. The problem lies therefore with the lights off, with temps reaching 18C, I brought the tube heater to help but having measured it at its peak, it gives off ~80-90C. Without the use of a thermostat plug in or probe like root-it, how would one go about using a timer to generate heat inside the tent? Would a 30 min on/off for the 4 hours lights-out suffice?
