Hmmm well I'm used to putting the roots on top of the sphag, but this one came from Ecuagenera with the roots underneath and I didn't touch it.
Maybe that has to do with it! But my plants looks as healthy as can be...
I think it's more related to the small space I have and not enough fresh air coming in. I've had about 5-10 spikes over the last 2 months forming up and losing their buds
Also, I have a bigger fan that's blowing probably to hard on the plants. I mean to change to 2 smaller rotating fans on top and bottom of the greenhouse, but I haven't got round to buying them...terrible!
