Question on growing indoors in soiless media

benitochibaJune 27, 2009

Hello folks,

I have a number of nice rexes, and a few canes indoors under flourescent lights. I'm trying to grow in a mix of coir and perlite.

I'm wondering if anyone has helpful information on feeding, PH levels etc.

I have a good PH/EC meter so I can easily manipulate feeding concentrations and PH.

What would be right PH and EC for feeding my rexes?

Thank you for reporting this comment. Undo

Most advice I've seen on feeding is it is safe and recommended to use slow release every so many months or when repotting (whatever the manufacturer recommends) and/or a weakened water soluble fertilizer used every week or every watering when the plant is actively growing.

PH is another matter. I have never seen any strong recommendations on that. Neutral would be the safest bet but a lot of species begonias might grow in slightly acid soil while others are growing on limestone formations. So I suppose it depends on what you are growing. Most begonias seem very adaptable.

I've never seen any begonia article concerned about EC levels (there may be some article out there but I've never seen one). Flushing the pot every once in a while or repotting should remedy any salt build up.

Humidity seems to be one key factor for some exotic begonias. Drainage is another key factor (too wet leads to rot).
