That's odd, but hey, I haven't tested it myself. I think running the same test day after day and at the same time of day is the only way you'll get conclusive results on that one :peace:
MH is a little hotter than HPS. In reality they both burn above 390'F, which is damn hot, either way.
A little closer to the canopy, 250w will garnish your plants with nearly as much light 400; say, 18 inches away rather than 24; and that's viable as it produces less heat than 400w.
400w/m2 is...
plants are breaking, arms are breaking too; a universe in balance. Jk! Koyaanisqatsi ftw!
Bandage dem snapped colas up and they'll recover nicely? Also, you can genocide the nanners before they get a chance to Joseph Fritzl on your pistils?

I'd like to add to Rico's fair point; one windowsill plant alone will still get you a criminal record in the UK. I hope that is a really old bank card, you're not really in Teeside and you've photo shopped someone else's back yard into the photos. Play it safe. Take it easy.
Germany is like Britain with the law and leniencies. As long as you're cool about it, you won't get bumped. Getting weed in Stuttgart will be like getting weed connections in any big city. You'll need to get chatting to the right people - bars, beer gardens, head shops, skate parks, local spots...

Your plants are somewhat reaching for light as lumen penetration is relatively low. That's why they're a little tall. Outside they would have better air flow than by your window and would receive more hours of more direct light.
As to getting a yield, increasing the light significantly is your...
