What are you growing? bagseed i would presume. If it's your first grow i kinda think you should grow bagseed as a trial run and then get some good strains in once you know your temps and humidity levels are good, can keep up with watering and feeding, plus you are even able to get a yield. strains may get a little expensive for seeds.

i'd grow more than one plant, because theres a 50% chance it's going to be male, and then you don't get any herb :[

good luck man hope everything goes okay
