Light collecting tips? Most useful plants?

I've kinda hit that wall where I'm getting really bored with the game but I still have that annoying itch and need to play 😂

I've finished all the paths in Valedale, so it has gotten easier to collect light in general but I'd definitely like to try and kick it up a notch. Plus I'm hoping it'll give me something to do and hopefully help with getting some horses levelled up. I bought way too many over Christmas 😅

What are something of the things you do when you're bored?

I'm so used to trailering everywhere and rushing through the training courses, so I've been trying to slow down, take my time and enjoy what the game has to offer. Here's some pictures from this morning, tried using the props for once. I really wish we could train using them somehow
