My first grow. any advice

this setup is going in a room with height 8 ft, length 70 inches, width 58 inches.

i just have a Rain forest 66 modular 6 pot with a T5 54W sun blaze 46" 6 lamp fixture. I got the hesi hyrdo starter kit from hydrogrowerUSA has any one ever used any of this?

i have 2 critcal kush and 2 white widow from seedsman. going to germinate with paper towel method and transfer to rockwool. i just purchased an electric ph meter to get my ph to be at 5.8. i will check the ph in the am and the pm every day. how should i adjust the ph lower and higher.

how important is a fan i was going to get one that has a temperature gauge and set it to 70F
Any advice on how to make this a good first time grow?

To adjust ph get some ph up and ph down from you local hydro store or on line, a fan is very important, plants need constant air circulation constantly for 24/7, I wouldn't get one with temp gauge it will shut off once temp is reached meaning air will stop circulating for a while, not a good idea....good luck with your grow my friend.

keep it simple. Don't get discouraged, work at it, limit changes and observe what effects your action have.

You've got all the right parts; get goin'
