>>962335>Where's the cheapest place to get pH strips?I don't know where you live. Usually a pool supply, garden supply, or you can DIY how to do it with household items if you google how.
They are very young, that is why there's barely any root system. What you see above ground is indicative of what is below ground. Not much up there either.
>>962400There needs to be a drain hole, otherwise it will not work properly. If you have a seriously tall pot, you can fill the bottom 1/3 with gravel and it will act like a self-watering pot. Some people do that by using a pot with holes in the bottom set into a pot that holds water at the bottom or cup-in-cup.
While these methods do work, I prefer there to be full drainage. That way as the water drains through it pulls in fresh air much more easily.
>>962381>>962394You do realize this is a real thing right? Many people use urine as fertilizer. I do. Although, I pour it on the compost pile. Most people use it directly by diluting it in a ration of 1 part urine to 10 parts water then watering their plants. It is actually a pretty valuable resource.
