OK guys, the problem is that I didn't have so much time to buy those lamps and i dont even have the sockets for the lamps.
I live in Slovenia, we don't have walmart, so I have to go by bus to "Bauhaus" and buy those lamps there. As for the box, I don't have any old computer cases but I am planning on moving the plants into my closet so as little light as possible gets wasted.
I will go to Bauhaus as soon as possible and buy the sockets and two 35W bulbs but I will keep this light that I am using at the moment. It was too expensive to just stop using it. I am planning to keep the current light on top, as for the little ones i will put them to the side.
The plant was transplanted and the most of the stem got burried under the soil to develop the roots. The plant isn't stretching anymore as I have the light very close to the top, about 2 inches.
Here's a photo, thanks
