I've always had a sick fascination with people that get so caught up on their own growing techniques and situations that they refuse to consider other methods might actually be as good or superior, depending on the individual grower's situation. Suddenly the ego gets kicked into high gear and "this worked for me" suddenly turns into "I'm right and you're wrong" or at least "my system is optimal and yours, while it will work, isn't nearly as good".

I've got grow going now with a strain that loves a LOT of food. It thrives at a TDS almost 30% higher than most other growers use. I've used distilled water for all my grows and yet every single time I've run this strain, it ends up showing cal-mag deficiency starting around day 10 of 12/12. By the time it's finally ready to harvest, the plant looks like a two week old corpse.

This time around I'm taking Stinky's advice and using tap water (mine runs ~180ppm right out of the faucet). I keep a bucket of water sitting under the sink to allow the chlorine to evaporate and I've been using that to top of my reservoir. I'll let you know in about 3 weeks if the tap water makes any difference.

But, no, distilled water doesn't always make for a "puuuuurrrrrrfect" grow.
Help_Needed Reviewed by Help_Needed on . pH in hydroponics (auto-drip coco)??? I recently got my plants a hydroponic system, but keeping the pH level in it at 5.5 - 6.0 is really difficult. The water with nutrients in it is at about 6.8, and then we add "GHE pH down" which lowers it to 5.5 - 6.0. But after a few hours its back to 6.5. Could the problem be that the plants are eating up the nutrients and leaving the pH closer to clean water pH? :P And should i just leave the pH at 6.5 ? Oh btw, plants are just about 10cm tall, growing a bit slow compared to what i'm Rating: 5
