I live in the UK, in Wales. This time of year there is mostly cloud on each day. When there is sun, it is still too cold to put my Vft 's outside, so i put them on the sunniest window-sill. I manage to keep the temperature in the aquarium in which they are growing to 20 dc and above for most days.
The problem is i don't think they are getting enough light, whilst they look healthy, they could be bigger. I also want redish traps. I need to invest in some artificial light source i think. I have no knowledge of what type of bulb to use, or how close to the plants the bulb needs to go.
I need help plz.
