To test the ph you should get a soil and water tester. This lets you know what your doing to your crop when watering it. Then you can test the soil every now and then to watch it. You could also get some ph adjuster so if its spiking you can get her under controll. Get a fan in there, a small one will do, angle it so it blows down or upward off the walls. This will create a circulation of the air in a small space. Its what i had to do. Hope all this stuff helps you man,
