Our prayers were answered! Honestly, I'm not sure how well the plants would have done if it hadn't rained during the week. We got enough rain to keep the temperature and humidity just where we needed it for most of the day. However, at night, it was a big hassle because water got inside the greenhouse, affecting the humidity big time. After that, it was super hot, so the water evaporated quickly.
Transferring the plants into bigger pots was pretty simple, but I definitely recommend the process for outdoor plants ONLY. This whole experience has been a learning process. We gave them nutrients a little too soon, but since we were able to catch it, we've only been giving them water and nutrients once a week moving forward. We've also been spraying them with neem oil since we don't know what could be festering in the greenhouse by now. Nevertheless, the plants are thriving and starting to grow more than just three leaves... hehe.
