I got temperature problems to, I heard that buying a thermostatic oil filled raiator was the best. you Just plug in set the temp and away you go. so I went out and bought the most exspensive radiator their is with electronic climate control (ECC) and blah blah blah. The thing is the cost of the electric it use's. And then I thought I would of been beter of getting the cheaper oil filled radiator. And now I,m thinking of postponing my hobby until better weather comes the only thing is I've just spent loads on seeds and have spent alot of time on mother plants.....time and money.......what's a grower to do........even with lights on the temp is only 10-15 celsius aahhhhhhhh !!!!!
