You have gear.
But not the gear you really need. Some if that stuff you got you need to sell and get the right stuff.
First you need a plan. How many plants what style. Okay let's say 4 plants a 1k hps. Veg total of 4 weeks +1 rooting clone or +2 from seed.
Really cloned do fine next to cfl you can fit 6 party cups next to an 18w for and the roots will fill sufficiently in 1 week to transplant to if final container. In my case 5 gallon bucket. It gets 3 weeks in that bucket with 7 others (8 total) probably will get topped too. By this time they are 2-3ft tall and ready to flower. I have 3 areas. Each are very simple. The first as above cloning and veg. It's about a 2x4 area, enough to fit 8 plants in buckets, a fan pointed at them with a 200w light above, then to conserve space because they don't very tall I built a shelf, where I clone, and veg for a week in small pots under about 50w of cfl
ventilation will always vary but the goal is the same old air out fresh in. I don't bother with co2 anymore. Grow in basements pull air from floor above. But you dont have to pull in air at all if you do just be sure exhaust fan is more powerful, giving considerations to filter restriction. A good rule of thumb is replace you air at least 3x a minute. I grow in roughly 5x5 area and use a filter with my fans and its about 200 cfm this is about average for my Space I draw air from the highest point. As close to light as I can and use as little ducting as needed to get it where I'm going. Recommend insulated.
Then a big fan,.box.fans are great. To both blow plants an hood and bulb. Bare bulb is the way to go. The 400w hangs vertical in both my rooms 1000w horizontal with a good in one vertically with parabolic in other. Im currently Comparing them
8 plants total in each room 4 plants spend first 4-6 weeks surrounding 400w with 1000w adding its light several feet away. This keeps them short, bushy, with even easily managed canopy. Then as something gets out and they start really flowering they are moved under the 1000w for the last 4-6 weeks. And they just pack it on from there.
Pro mix feed every other watering half organic half synth. Flush x2 last 2 weeks.
Keep humidity low. Watch for bugs. Research experiment and figure it out.
