I'm Raymond we met at icps at Cairns. I had a small wine fridge growing neps and helies but in Jan this year I moved them all into a much bigger cake display fridge. Ever since I moved them most of my helies are dead and even most neps turned black. I've found helies will die the next day even if I kept the temp at 22'c for only one day. So I'm keeping the tem at 17-18'C max during day and 9'C at night.
They were doing very well in the wine set up.
The new cake display fridge.
It's too late for all my helies, I have to start all over again.

It was the same thing with the wine fridge if I let the temp gets to 22'c something would die the next day. My 6' is a little bit better when the temp gets to 25'c, even the hybrid neps would start turning black and die.
No one in Sydney is able to grow helies or neps sp. Only one person moved up to the top of the mt is able to grow them.

Raymond yes mate remember you from ICPS conference. ,that's interesting , that helis dont grow in Sydney, would have thought it would been all most easy to grow them there??. why u using LED though ?? i cant grow squat under LED , thats my fist step in your problem ! in my experience so far , it just makes the plants weak and go back wards ! u using Town water or rain water ! whats the mix your using now days ,same as we chatted about all that time ago?? or !
start there first
Red lowii (Marcus)is in Sydney , he growing neps outstandingly well ?

ok checked with a few guys in NSW Sydney area, they grow there helis in a G/H out side H/L ,and both do well you know both Raymond, Glen and Jose ,so for me its your lighting making them so weak and unhealthy plants and may be watering possibly too . If it was me would change your lighting to grow lights not LEDs or supplement the LED with proper Fluro grow lights for me would be the answer , or just grow them out side in a shaded 50% or less G/H with rain water watering and evap air cooler if needed. that is what I be doing ! but u would need to do it slowly as the plants are weak and need to be harden back up again . any others got any suggestions ??
Thanks John, I don't think it's the led lights cos they were growing really well before. They had new leaves 1/4 bigger than the last leaves and they wrere showing red colours so that's how I know they are gettng enough light. I use led lights cos it produces less heat comparing to fluorescent lights. I'm guessing it's the night temp getting hotter and hotter every year. 20 years ago no one needs a/c to sleep at night but now the highest night temp was 30'C last year.
I live in an apartment so G/H is out of question. All my plants get their water from the humidifiers so it should be quite pure. I did used a water sprayer to spray them with tape water twice a day in Jan (during the hottest time of the year), maybe that might be the reason. I think you get much lower night temp than Sydney. I potted them all in pure sphagnum moss.

ok Raymond really do not feel its the temps ,as in summer our night temps rarely get below 20 to 25c , and days as you know well above 35 to 40 c +++++ and humidity can get as low as 1 % but in the G/h is still around 50% with misting and water cooler , , , I think best to try the lighting first and get a good size CP fan in the tank for air flow too , if your using fluros it helps to keep the air cooler too just by movement. also many people here have to grow in tank set ups and may give much better advice than I with tanks growing , i tried it and for me was a waist of time and $$ cause the G/ h is just 100% so much better .
All I know is in our winner they grow so well I never have to look after but in summer it's a real stressing for both plants and me just trying to keep them alive. At the moment they are doing really well but it's because it's our winner here again.
The only explanation I have is with terrarium the lights have to be close to the plants in order for the plant to get enough lights but lights produce a lot heat and that heat needs to be lower or takes it away from the plants. It's becoming like a sauna and the plants are being cooked. You don't that problems in a G/H.
Thumbs up to John for growing heliamphora in thought-to-be impossible conditions. This just goes to show that as growers, we should try to get plants to adapt to our growing conditions rather than trying to mimic every aspect of the natural environment. Honestly, my Heli's start sulking at 26-27, I can't even imagine a heli in 30 degree temperatures ha.
Funny thing is, I have some bicalcarata that did fine in 18 Celsius during the winter even though they very warm growing plants.
