Hey man, just checking into this thread again, as I (inadvertently) have basically copied your entire setup.
We already had the 4x4 tent , 1000HPS, and Sentinel in common, and now I've switched up my plan from buckets and have a Botanicare 4x4 tray in there to run E&F.
Ironically enough, I'm also a disciple of Lucas (I swear, I'm not your stalker
).
However, I'm gonna put about 25-30 plants per tray in 2 gallon pots with hydroton, as opposed to rockwool (only difference I can really see).
Anyhow, if you're still checking this thread, had a couple of questions for you - #1, do you have an RO filter? Also, how often did you change out your res? Did you do every couple of weeks or did you just top off for the whole grow like Lucas does? How large was/is your res? Did you use the 0-8-16 of Flora or the 6ml of Floranova?
Sorry if these questions were already covered in your thread - I read the whole thing a few weeks ago but don't recall if you answered these questions.
Thanks for your time, and not to scare you or anything, but my next setup is also going to be a 4x8 tent with two 4x4 tables.
Weird, huh?
