Active hydroponics requires a pump to supply plants with hydration, duh. But I have killed so many crops that I have pretty good reasons why it happens. Sometimes the fault lies in the machine, but usually fault lies in man. So maybe others too can learn from my fuckups. · Never go a day without checking on the crop! Complacency syndrome is a killer. High performance hydroponics comes with high frequency checks. · Assumption is the mother of all fuckups. Never assume things are fine just because they were the last time you checked. That last time could have caused something to switch off. This has happened with every crop loss. · Flipping switches and settings are sacred events, they become like your basal life settings, each and every operational state must be minded with highest care. The “Oh fuck I forgot to switch the pump back on” can easily happen after tedious res changes. · Like piloting aircraft where people’s lives are at risk, you are piloting a hydrocraft where plant’s lives are at risk. · The pump is the greatest weakness. Of many possible factors, it takes only one to kill it: dodgy timer, loose connections and plugs, frozen impellor, blockage, are all things that have killed my crops. · The pump is like your heart, it dies, you die. A beating heart is the price for improved oxygenation. · Distraction is the father of all fuckups. Holidays, people, studies, work, personal issues etc. can undermine your mindfulness for plant-care.
