Two seeds in Machinery grounds

[Penrithjon]

I spent 4 hours locating two difficult seeds in the machinery ground. At the machinery grounds there is a path to Heavens Stair. (get to it by using red plate at the fertile grounds. You land at the intersection where if you follow the wall you reach the Construction yard. Heavens Stair is the path away from the wall.) Take this path way from the wall moving from poles to platforms and walls. You reach the two red slides and beat the generic corruption enemy. THEN, GO BACK TOWARDS THE WALL taking the first red slide. Jump to the vines on the first wall. Gripfall down to some vines below and follow the vines to the left for two well-hidden seeds.
