Those are some lovely plants. I also see you have a few sarrs flowering in the background. Nice.

I found that Utricularia calycifida and my two species of genlisea do not like to grow in sand. I replaced sand with peat and they started to grow better. I think it is because I was unable to deliver enough nutrients via leaf fertilisation.
Other plants that grow in pure sand are fine :)

Wow! I have been looking at peat-free means of growing carnivorous plants for some time now, will definitely try this out. Even using standard mix like this, it seriously cuts down on the amount of substrate (and then peat) that you would need.

I wonder if weak nutrient mixes, low in nitrogen, would make for a good additive for this, or at least trace elements? At scale this is probably a fantastic way to propogate sundews as well. I may try this with some wild capensis forms I will be collecting soon. Thanks for sharing!

I tried to add diluted fertiliser to water and it never worked for me. Water and sand were becoming green and plants did not grow well. Carnivorous plants are adapted to very nutrient poor environments so they can grow in such conditions if are fed through leaves.

The only compound I add to water is potassium hydrogen phthalate (KHP). This compound is used as pH buffer, it stabilises pH at 4. It is very nice feature of this compound because even if you add a lot of it, the pH will not go below 4. It is also a source of K for plants. In one of my previous posts I wrote that I had observed signs of K deficiencies in some sundews. These signs disappeared after adding KHP.

I do not recommend adding KHP yet because I do not know what are long term effects. I did not observe any adverse effects so far.

Ah okay thank you! The KHP seems to be an ideal solution for keeping the water acidic as well as provinding potassium.

topic51264.html Would you mind lending your thoughts on this? Some drosera are not a fan of being permanently wet so I don't think this method would work for them (ramentacea, hilaris etc) so perhaps a low-to-no peat mix would be ideal.
