For your first grow you want to flip to 12/12 early Like if you have clones, let them veg for two weeks then flip, just so you can see what a plant does through the whole cycle. Write everything Down, trust me you wont remember later. Then again I don't know you but most people will forget.
Make errors fertilizing on the light side. Too much fertilizer will really screw things up as will trying out all the new wizz bang sure to make super bud products out there. Learn about one at a time and try them on your next grow!
For this grow you need to absolutely learn about the total environment that you need to keep these plants in for their whole life! How much light, humidity, temperature, how much water, how much outside air, Fans... Lots to learn without complicating it with crazy products. I like that you have the simple stuff to start!
MOST IMPORTANT!
Read the infimarary section: Don't end up in there... You will don't worry but you can head it off at the pass by learning and know what something bad looks like early on.
Never visit your plants when they are sleeping. 100% dark is the best policy. I don't care what anyone says about green light. Plants can grow in green light, look at the photosynthesis curve! You don't want hermie plants.
