Woof!
Ok I moved the perlite ones to a different place, closer to the sink, where they will catch indirect sunlight, and light from the kitchen. It should be easier to work with water there anyway.
I guess we will see how I do.
not really. it averages 20 to 24c tops in winter. i have a small heater in the veg space as it isn't really insulated well. i keep all the heat from the light driver bottled up in there as well.
