It's not that I don't ever need help, it just happens less often now. I'm still learning every single grow. I say if the app works for you, then definitely use it. Most I've seen that do keep a grow journal use a more traditional method like a pen and notebook, or they keep a file on the computer. The main reason I didn't use it is because I didn't know the start date of my grow at the time, and then I forgot about it. It definitely gets easier as you go, but you can still have problems come up that you'll need help with. I've been doing this a few years now but I still read through the new posts to educate myself more to be able to help others. Anyway, from what I did see I could tell it's a pretty good tool for keeping a detailed log of the entire grow. And you can always refer back to it if you grow the same strain again for nutrient needs, heat/cold sensitivities, water and light requirements, etc. I mostly try and keep mental notes of what I've done, but that's not as reliable as writing it down. I may try and get it figured out when I start a new grow (hopefully this week), that way I can keep a more accurate log from start to finish. Happy growing!
