Has anyone attemped growing Nepenthes (highland or lowland) in a hydroponic environment as this is an experiment I would like to try with my nepenthes ventricosa (highland). Somehow I think that it would not work with the highland and I would like this clarified.
From what I gather the average home hydroponic system usually consists of a few basic parts:
*a growing tray,
*a simple timer controlled submersible pump to water the plants
*and an air pump and wooden air stone to oxygenate the nutrient solution and provide humidity.
*and artifical lighting unless growing it outside.
Part of this system I have applied to growing the lowland bicalcarata with great results, except the lower part of the pot is kept submersed in water in a perlite medium rather than the whole pot. Is this right? Refer to my N.bicalcarata topic. I tried this on the bicalcarata (lowland) as a few websites mention that this species prefers a more wet condition. Would this setup be good for most lowlands rather than highlands?
I have read that perlite is far superior than rockwool because of something called capillary action which allows the medium to take up water as fast as it loses it through evaporation. And at least every factor including pH can be easily adjusted, maintained and checked including nutrients.
I used a systemic fungicide, 'fongarid' to keep away the fungus, every two weeks. Will this constant use of fungicide affect plant growth in the long run?
I then apply a small amount of fish emulsion and superthrive to the water in the resevoir every month.
Any advice would be great.
