6 quarts of water? Maybe consider getting some 5 gal buckets, cause 6 quarts of water is going to go fast, be a pain to put the right amount of nutrients in, and keep stable as when you lose 1 quart of water the nutrient level has now gone up by 1/6th, let alone 2 or 3 quarts, and i know a plant can drink that in 24 hours.
As for the actual question i run a shallow water culture system and i let the water go 3/4 or so up the plug, just make sure you have a lot of oxygen in there if you are gonna run it that high.
hehe yeah 6 quarts. what could I do with a 6 quart res? cause I killed a plant due to high ppm and ph levels, plus I think I over fed it with Spray N Grow.
But now, after changing my Res, My PPm is 102 and my ph is 6.5 with no nutes. The water is filled up to to keep 3/4 of the net pot submerged in water.
a seedling is in an organic seed starter plug, has been for a week, and in 1 week probably around 2-4 cm of water had evaporated in my res. im starting to wonder if ill have to had water with a ph level of 0 to the water each day just to make sure its always at the right water line.
For now, the seedling, thats one week germinating (which means its a seed trying to grow into a sprout right?), and now with a new cleaned res with no nutes im keeping the light on 24/0 for another week to see how tall the sprout grows. * oh by the way, when I put in the seed into the new clean res, I noticed the seedling had a little sprout just barely showing itself. I hope to see good results this week, but not without some help and my own common sense hehe
