Just an observation from my experience with growing in bales (very limited) 150 days until planting time is quite a bit. Those bales will continue to break down from now until planting time, even more so once planted and watered more regularly. You may come to find by mid season or even earlier depending on decomp rate, that those bales are "melting" and completely falling apart. Its natural for them to lose shape as times goes on, and in our long CA growing season it did become a challenge. Maintaining a viable planting medium could be difficult for a larger size pepper plant.
Again, just an observation from my own experience. I will be following along, good luck to you!
I remembered your post and wanted to follow up with you.
You were exactly right. The bales melted down to compost long before planting time but I think it's probably a good thing. Now my bales are a thick layer of nicely composted material melding with the ground below. If you haven't seen it, there's a picture a page or two back of what the bale insides look like now. Before planting I decided to squish the bales down flat.
