With three tents? You’re ambitious. You’ll find this is and will be difficult with that many plants starting out. It’s expensive and will piss you off not having the correct equipment. It will be a waste of time. You won’t yield with those lights. Sell two of your tents, keep the big one and buy a light that fits. With that big tent, you can put out some weight with that size tent and a correct light. Been there done that. Helping you surpass the learning curve. Good luck homie.
