First-timer with a full Mars Hydro setup (TS 1000 & 80x80x160 Tent)

Hi everyone! I waited my mid-forties (and a divorce) to buy me my first growing tent. I choose the full setup by Mars Hydro on Amazon (the one with the digital device), which was the most interesting ratio quality/price that appears to me at the moment. And add it a couple of oscillating fans. We'll see if I need a fourth one. I'm afraid I start with to much plants and that they'll quickly be out of place. Because as the seven dwarfs of Snow White, I decided to begin this adventure with seven unknown auto flowers that a very good friend of mine gave me... Let's call him Mister Smee 😉 He once advised me that it was the best way to start : try different techniques at the same time, eventually screw up one think or two in the process and learn from the done mistakes. It's my very first time, and I didn't wanted to waste some "real" good seeds, that's why I decided to practice with some hybrid ones... Wish me luck on this new journey ! And don't hesitate to guide me a little bit or give me advices, I'll be glad to read it all 🧐
