I have a grow box in my basement with a 6bulb t5 fixture. The 3 plants I have are 20 days old today and so far are looking great. I'll start out by telling you how I started. I told my wife to get me some soil and plant food when she goes to the store. I had not been reading a lot on what to get so she had no idea. She came home with mg garden soil and mg plant food. The soil has the time released fert. I planted the seeds I germinated in the soil not knowing not to use mg products. Well I figure I better not change the soil now and just hope for the best. Like I said the plants are doing great so far at day 20. The question i have is do I need to nute them or just leave them alone since the soil has fert. already? Also, I would like to post pics of them but I am not sure how.
