the main stem is about the same size as a wine gum.
they are just like normal bulbs that you would get from a pet shop etc.. its not the tube like the one above the seedings.
ive ordered a HPS 400w Lamp, more than i wanted to spend but reading up on it it will more than pay for itself in the difference i guess...
i do have a fan on the plants but is out of the camera shot.
the actual hight on the plant is upto my shoulders nearly which id say was pretty good i guess.
new lamp should be hear at the end of the week so will let u know how i get on..
