Saving or using the seeds

Touch the filled in blocks (energy blocks) on each side, then you get enough jump height to get out of the room.

Jump left, touch both energy blocks, and get back to the middle "platform", jump right, touch both energy blocks. Done.

I was able to ride the elevator past the currents by not turning the currents on (so everything is still dark), even without the streams the final jump was a little tricky. You've already powered up the room permanently, so you don't have that option... The best I can say is stay to the left edge of the elevator, push left as the elevator takes you up into a stream, and have the cursor lined up to teleport over to the platform on the right as soon as it gets into view.

I just tried this approach myself in this room with all the lights on, and its tricky but not out of line with some of the other dexterity puzzles in this game.
