Hi All, Another noob post looking for advice. I'm working toward a relatively simple first grow and have already modified my plans a couple times. I tend to spend more time reading and thinking about all the things that could go wrong than I do actually getting started. I am pretty much out of excuses though and need a little assistance tying up loose ends. Here's the setup: 8x Cree CXB3590 @ 400W on angled aluminum 3500K 2x Meanwell drivers HLG 85-1400 6" Hurricane Inline Fan 6"x24" iPower Carbon Filter 4x4 Apollo Tent EcoPlus 18w air pump W/6x manifold 6x Large air stones 3x 5gal black bucket + 6" Net pot lid 3x 10gal tote (1x per bucket for cooling reservoir) Advanced Nutrient PH Perfect 3-part Advanced Nutrients boosters I plan on running 3 DWC buckets with 2 air stones in each one. Originally was going to do RDWC or even just a reservoir but I really want it simple and want to limit the chances of killing all three with a single mistake. I have seeds from Nirvana, Northern Lights Fem. I chose these as they are supposed to be forgiving to mistakes but still yield well. I will be using Hydroton (or whatever knockoff I bought on Amazon). I have rinsed/soaked these well as I did the air stones. AN PH Perfect will be my nutes for this for simplicity and I'll be using RO water. My 4x4 tent is in the garage, tucked into a corner. I have access to outside air for intake but not really for exhaust. I've been running some lettuce I do Kratky style in the tent just to get an idea on the temps. I am running around 72-79f during the day, down to low 60's some nights if it's really cold out. Some open questions - 1. What do I do for intake? I'm using LED so I don't have air-cooling. I doubt I want to just open the bottom vent, seems like bugs would come in. Also, light escapes in/out if I do this. 2. Buckets are new from Home Depot. I let some fresh rain water sit in them for a few days just to clean them out a little. Is it necessary to sanitize them prior to use with alcohol of bleach etc? 3. I'll be starting seeds in Rapid Rooter plugs. Recommendations on best method? When do I move from the starter tray into the bucket/net pots? 4. I have 3 rain barrels that I use for my garden. Would this water be good for DWC? PPM is around 14-20 so low. My concern is that it does sit in there for a while and there is algae on the sides sometimes. Am I just asking for issues? 5. Using Advanced Nutrients with RO water. I've been to their nutrient calculator. Should I simply start here (at 1/2 strength) or is there a better known mix? 6. Anyone have a good link to where I can find some sort of printable schedule for temp/humidity/feeding etc that would be helpful? Sorry for all the questions, I'm sure this won't be the last time. Thanks in advance for your help. edit: Another question. Should I start my seeds under my small 12w LED (blurple), larger 130w LED (blurple) or my Cree's dimmed way down?
