Hey Square how you gonna modify it? I wouldn't suggest it unless it's something small. I mixed my kfb grow and part of DDs and I'm kicking my self in the ass. I used a too small a pump and therefore not enough flow and now I have root problems. I changed it but once you get problems there hard to fix in this system.
well :) I plan on running some tests, mainly to make things more efficient, and of course for my own personal space restraints not allowing me to go 'all out,' like D does.
Of course, everything I am thinking of is theoretical, hasn't really been tested so I may fail in which case I would just move closer to D's system and live and learn. If I could make some slight improvements I would be happy to contribute so. My mindset is efficiency and simplicity, which is not exactly 'being cheap,' I know D's mindset is "all out" and "go large" and "don't skimp."
For example, if you get good results with a 2000 gph pump, could you get the same results with a 1500 gph pump? How about a 1000gph. Would a 3000 be better even?
This is an example of a type of tweak or modification which I hope to zero in with this system.
A few specifics, I am considering trying to replicate this system using only 1 pump (including chiller), and basically trying to have gravity do a lot of the work. I am working on alternatives to the connectors to actually connect the tubing to the tubs/buckets making this area foolproof. Finally, I hope to run my test nearly exclusively using induction lighting, to see if this type of lighting is effective at growing.
I'll definitely make a thread here in the next few days to start documenting my trial run, just waiting for the lights to get shipped to me now, I have some babies in a cloner waiting to be moved.
