Helf with waterfarm

[Justin12421]

How long can you leave the waterfarm unattended for ? is 1 week possible? Thank you
Im planning on using 2 waterfarms a 270 watt cooltube, panasonic 190 cfm whisperfan, two computer fans for circulation with 2 feminized grapefruit plants saved from years ago inside a 42 inch plasma cardboard box.... what do you think? will have pics and stuff when everything comes in. Its all ordered just waiting for supplies.
Also you think i could do 3 waterfarm. ? will have dimensions of box later when I get home.... Thanx in advance...
Oh ya after the grapefruit... Cause I need some nugs fast and its a 10 week from seed plant i will be growing white rhino then I thought id give the publicly known northern lights a try...

A week could be possible so long as pH was properly buffered and everything was set on timers to keep the environment stable. Usually, I check pH and have to adjust every few days or so with DWC bubble buckets which are in a way very similar to Waterfarms. Also, make sure you have enough solution in your res to last well over a week. I like the lucas formula for nutes with RO water; pH seems to stabilize quickly with little or no problems. Good Luck
