Hello and welcome to the forum. Thanks for your input.

I think that your idea is definitely doable. I would probably try 250W HPS from above, and then some bluish LED's around the sides. I think that if you spend enough money on the LED's the yields would be similar to your one 400W HPS. Please be sure to let us know how things work out if you decide to try LED's.

Are you German?
