you didnt mention if you are doing hydro or soil. but here is a good post that lucas creator of the lucas formula wrote.https://www.cannabis-world.org/cw/showthread.php?t=360 it is a good post on some of the requirements you will have for a hydroponic ebb and flow grow.
You need to do a lot of reading. Seriously, don't spend all that money and time, and jump in not knowing what you are doing. No one is going to reply with a detailed journal for you to follow step by step, all that info is already here on GC. You need to do some reading here, then go check out the grow journal section. Look for a setup similar to what you want to do, then read that journal. He/She will have all the details of the setup, issues encountered, how it was resolved, all the stuff you need to know. If you start to grow now, it will likely be unsuccessful as based on your questions, you do not yet know what you are doing. So take some time and educate yourself, in the end, your buds will thank you for it, and you will not have wasted months of your time battling nothing but problems. Good luck. Peace.
