On one of the YouTube channels that I watch frequently about gardening (Praxxus55712 - subscribe to his awesome channel!) Ray talks about using clear seed pots to start his plants so that you can see the roots. I am a big recycler and also "thrifty" so I came up with this idea. I just took an empty water bottle and cut it in half. I think I can plant in both parts. I will post more about this idea once I start using it.
