Quick Semi- Hydroponic Course

Because fish excrete plenty of nitrogen, Seachem has very little. Nitrogen is THE most important nutrient element.

There is very little overlap between aquatic plants and those grown in S/H culture, so stick to standard products for them.

I reed a few products, some of them claims to fertilize and desinfects the water, avoiding algae production and relieve toxicity ...etc etc

Hello!!!! Happy summer to everyone.

Regarding orchids species, I think I am having an issue with some dendrobium hybrids that shivering for a dryer setup.

Any comments on this? Is it just me? or has anyone experienced low progress with Dend?

The rest are all fantastic, Catts as soon as the weather warmed up..have been developing very nicely and all Oncys and Phals are great.

Sorry!
I want it to post in this thread!

Thanks Roberta.

Mainly the Dend no working well are hybrid from Dendrobium johnsoniae and Dendrobium polysema
