yeah i only got to try the light on for 30 mins till 5 oclock as lights off for me is between 5pm and 11 pm,doin the 18 on 6 off thing,but had to keep both doors on wardrobe open with a large table top fan blowing in and the temp was settled at about 92f which i think may well be a bit TOO hot as a cant put the fan on full power or itll just about blow my seedlings out the soil although on low power theres a fair bit of movement with the stems which i heard can be useful for strengthenin them up,although not sure if its a bit early for that yet
