Hey everybody! Glad I joined such an informative group! You guys know your stuff. So here goes, i have a few questions…This is my first hydro build and grow so take it easy on me please. Lights will be 2 spider farmer sf4000 and beans are Ethos. GG4, lilac diesal, and citral glue (grabbed a few options)
So first thing, i see almost all rdwc systems pull the water threw the system. I feel like id rather push it threw. That way anything floating around will end up in my res tank instead of going directly into my pump. I’ll have some type of screen in the res to prevent anything going into my pump. Seems logical to me but most systems pull the water threw and “waterfall” it back into the res…Is there a downside to pushing the water instead of pulling?
Next question, i bought the danner hydromag 950. If my calculations are even close then i will be moving water 15-16 times per hr. Ive read 7x’s an hr is good. I know it may be a little less due to 90° bends and roots slowing things down but does 15x’s an hr seem too much? Can it harm my roots?
Next question, i have the active aqua 1110gph air pump with 5" vivosun round airstones. Is my pump big enough to run 8 5" stones. Im finding mixed answers in my research
Last question for the day, haha! I want to run CANNA AQUA nutrients. They seem a little expensive in a 60 gallon system to change out everyweek. Do you need to flush everweek? Or can i top off if everything looks good (ppm and ph)? Also, they have an additive called CANNAZYM. Its for root health but i feel like i want to run hydroguard for my roots (based on high reviews during my research) Now would i run both root nutrients (cannazym and hydroguard) or pick one?
Thanks in advance guys! Sorry to be a pita my first post but ive been researching for a couple months and want to make sure everything is gonna be doing good my first go! Very excited about my new venture. Cheers!
