I'm a first timer, so I'm obviously going to have some questions. After reading about growing for the last 10 years or so, i decided to give it a shot. I spent the last 3 weeks in this forum reading everything I could (THANK YOU ALL), decided what would be best for me and went to the store. The guy talked me in to a few changes but I came out happy and spent a exactly what I wanted to. My space is a bathtub (about 2.5 ft x 4.5ft x 7ft) in a full bath. 400w HPS Digital Ballast (MH or HPS) 24x48 Tray Bag of Hydroton 30 Gal Reservoir Pump, Hose, Tubing for Drip system Smaller pump to circulate water in reservoir Long Airstone A box of the CO2 pucks that you put in water I'm 7 days in. Started from seeds. I planted 7 seeds from the steady flow of purple we've had for the past 6 months. All 7 sprouted, 6 of them made it. I started in Rapid Rooters, stuck the seed right in, pushed it down a little.... They're about 1 1/2 inches tall and are all starting they're second set of true leaves, one of them, which i think is a different strain, is 2 or 2/12 inches tall and has started it's 3rd set. Here I am 7 days later and I need a few questions answered before I can move on...i think. I took the plugs and put them in the Hydroton about level with the plug. They've been in the system since day 4 and I've been giving them about a 33% nute solution (technaflora products) all seems fine... I have the light on 24/7, when do I switch to 18/6? I don't have a dripper tip in the end of my tubing for each plant, it gently flows out of it right now, no splashing or anything like that, is this ok? I've been feeding every 4 hours for 5 minutes. How will that change once I start the lights on 18/6? I've read that I can water every 3 hours for 4 minutes but when it comes to using Hydroton, everyone seems to say something different when it comes to a feeding schedule. Thank you.
