I think it's Thai hot 80.000 shu

I'm doing an experiment with 2 cayenne plants, one with tap water and other with fish tank waste water

What does the tap water pepper look like in comparison?

Not much change yet but I only repotted them a few days ago, fish water one seems a little bit healthier

I'll keep uploading pics weekly if I can

So far it's looking good. I notice slight differences in the leaves but the height looks about the same. This is an interesting project. Keep us updated on their progress.

Will do m8, I'll post a pic every few days or so. It will be good to see the difference if there is any

How big is your tank to supply the volume of nutrient rich water w/ such regularity?

My tank is 330 litres

The cat knocked my cayenne plants off the windowsill but i managed to save them.

Takes more than a tumble to kill a pepper! :)

Was a nightmare cleaning it up, soil mixed in with broken glass.

I noticed that the root system is pretty bad on the cayenne plants when the cat knocked them off window and they haven't grown at all since I got them

What did the roots look like? Brown and thin or some other indicator? Also after being knocked over and replanted they may have transplant shock. Hopefully they turn out well.

Just really short roots for the size of plant but the compost I've put them in is a lot better quality so should make a difference

Did you add perlite or pine bark fines? Something to allow oxygen to the roots?

No just compost

The soil that the plants came in seemed really poor quality and felt really tightly compacted, could this effect the roots?

Yes, it was probably not the greatest soil the plants came with, but straight compost is not any better. Are there any pices of bark in the compost? If so you may be ok with using it, If not you may want to add perlite to create air pockets so the roots don't get compacted on and allow oxygen to the roots.

It does have bits of bark in it and it has been really good for roots on my cucumber plants, when I transplanted them last week they had really good rootballs

At least you have the bark to provide some oxygen to the roots, though I would personally add perlite to the mix because eventually the bark will further compost down, not as fast when in containers so you may be good to go. Your plants seem to like the mix.

kudos but is it the fish tank water?

Not sure but fish waste is full of nutrients for plants and my plants seem to thrive off it

Both are looking good! Guess after a few weeks maybe we will start seeing a difference.

The one on right got the worst of it when they got knocked off window sill so won't see true results
