What Water Source Should I Use in My Tower Garden?
Well Water
City Water
Your City may add Chlorine or Chloramine. Sometimes, you can find this information in the municipalities website, other times you'll need to give them a call. There is mixed information out there about the effects of Chlorine or Chloramine on plants. Some say it does not affect them, others say it does. If your seedlings were doing great and then you transplanted them to the Tower and they wilted, I would go out on a limb and say that your water source was more than likely the problem. Now bear in mind that not all seedlings may wilt. The variety and age of the seedling will be a factor. So what can you do about it?
Chlorine
Chlorine is relatively easy to remove. Read on as we discuss ways to remove Chlorine from your water.
How to Remove Chlorine
Let it sit in the sun for 24-48 hours
Fill buckets (food grade) with the city water and leave it in the sun for 24-48 hours. Over time the chlorine will dissipate. After a day or two put the lid on so as to avoid algae growth.
Chloramine
Chloramine will not easily dissipate and because of this more and more City's are using it to treat their water. It may stunt the growth and fruit production of plants. Chloramine, like chlorine, can be removed by boiling and aging. However, time required to remove the chloramine is much longer than that of chlorine. The time required to remove half of the chloramine (half-life) from water by boiling is 26.6 hours, whereas the half-life of free chlorine in boiling water is only 1.8 hours.
How to Remove Chlorine/Chloramine
Purchase an inexpensive filterA filter can be used to remove Chlorine. Prices range from $17 - $40 and a few examples can be seen below.
Chlorine Neutralizing Liquids
Boiling
Because of the time it takes to remove chlorine or chloramine from water by boiling it, it isn't a suitable solution for us!
Rain Water
Rain water is great however, contamination is always possible by airborne dust and mists, bird feces, and other debris, so some testing and treatment may necessary.
Reclaimed/Lake Water
Due to the possibility of contamination and runoff of pesticides and herbicides neighbors may be using in their yard we do not recommend using reclaimed water.
RO Water
RO is fine. Chloramine is removed by a carbon filter in your RO system so ensure the filter is not depleted.
