First time set up help!

Hey there! This will be my first grow and I am needing some guidance! My white widow feminized seeds will be here by 10/15. I made a grow tent in my closet and it is 5x7ft. There is a 2x3ft opening in the ceiling where I am building a ventilation system, and plan to add a carbon filter in a couple weeks. I have one 16 inch oscillating fan that sits on the floor. Is one enough for this space? I have a humidifier and planned to use it the first couple weeks during the seedling stage and then switch to dehumidifier for the rest of the grow. I have read white widow likes the heat will I need a heater? It is naturally without running equipment about 72 degrees Fahrenheit and 50-60% humidity. I have a 3000w LED light , I’ll post a picture below. Please tell me if this is enough to support five plants? I want to grow the right amount of plants that will thrive. I am wanting to do 5 plants, but I am not sure if that light is enough. I am using fox farm ocean forest soil and adding (25%??) perlite. I have a digital Ph tester and Ph adjuster kit. How often do you test the soil run off? My plan was to germinate, then plant in 2.9 quart plastic pots with holes in the bottom.. then at 3-5 weeks transplant to 5 gallon smart pots. Originally I was going to directly plant the seedling in the 5-gal smart pot, but I’m undecided.. just trying to find the best option. Also I had read that for watering the first couple weeks you’re supposed to use a spray bottle and spray a few times a day. I really need a good reference for a detailed watering schedule From planting to harvest. Please let me know what I haven’t thought of! I am open to ANY and all ideas and advice. Thanks everyone!

That light is only 480 watts so its not nearly enough for a 5x7. You will need at least 3 of those to properly cover that space.

Theres a lot of good basic info for new growers there.

That’s a pretty awesome light at 480watts input, you can definitely do 4-6 plants no problem, but hang it at least 36in above seedlings and veg switch on at first. The 16in fan should be just fine for air circulation inside the space. definitely get the exhaust system. ocean forest is pretty hot and I’d recommend using a seedling mix at first, then transplanting into ocean forest after a few weeks. I recommend germinating using the paper towel method, then plant taproot down into seedling mix in a peat pot that you can put right in the 5gal smart pot of ocean forest, pot and all. Be sure to water in intervals of moist to pretty dry after the first week where you’ll want to keep the soil moist.

Using preventative pest control measures would be highly recommended, like spraying neem oil regularly while they are in veg. also, I’d amend the FF OF with dolamite lime to help keep the ph in check and use water at 90-250ppm 6.2-6.8 ph without ph adjusters if you can. Check your run off ph regularly to help you figure out issues if they should arise. @chronnie49 has a good point, you might wanna consider more light. Rock on brother I hope you grow a pound
