good heat stress supplement

About 6 mths ago I started using Superthrive on my current batch of new seedlings...but to date I've not really observed anything that would make me believe that this product is a 'must have'. I used it as a trial to see if it would speed the growth of my seedlings in the first 6 - 12 mths when they are growing in my indoor set up. I would have thought that if the product 'allows' the seedlings to better utilise fertiliser, then they would grow faster, but my seedling growth rates have been comparable to the last few years results.

I'd also be interested to know if anyone has had any definite success with this product, and how it is used with broms.

I started to use some, but I have no idea how often to use it. I'm guessing twice a month would be enough. I'm not doing any controlled testing (too much trouble) so I won't really know if it helps.

devo, I don't imagine you would need to use it on indoor plants.

Since I've never used it for any heat ailments like HDD, I can't comment on that part of the equation. Otherwise, after using a free one gallon bottle of the stuff and seeing no definitive results on different genera of plants, IMO it's overpriced(?) snake oil.

its only a supplement not fertlizer...it will revive heat stressed plants quickly(within 2 hrs)...I use it as a soak.
Seedlings need food not a supplement

I figured heat stressed plants could benefit from it, that's why I got it.

On searching the web the most I found was people who got not much result. Some quicker root growth on grasses and a few orchid growers that were believers was the best I could find. People who grow pot seem to use it a lot over here. They also use it for stressed plants. (growing pot is our national illegal hobby)

I guess it won't hurt my broms if I use it, or do I have to be carefull with this stuff?

The advertising looks like the ones in 1970's comic books selling x-ray specs. That doesn't do it any good if it works.

one thing its never done is hurt a plant...no matter how strong I used it and I have used a 25% mixture on some rare palms to revive from a long journey...so I say without reserve it is not dangerous

I have used it for about a year now, I cannot see where any of my Bromeliads or Bromeliad seedlings have benefited from it, but my Clivia seedlings have. I have used it on some other things, but the jury is still out.

Since mine can have a pretty hard life in winter in the house and outside during hot summers I figured it would'nt hurt. I am still a sceptic. Thanks fot your opinion Seikomom.

Hi Sander,
the seaweed extract is generally known to help to protect from cold/heat stress. I use it, but as for all this stuff, a good, statisticaly significant comaparation would be needed to show whether it works or not.

I have this suspicion that Superthrive has helped initiate root growth, and made some roots grow thicker on my Tillandsias. I started casually spraying ST on my Tillandsias about a month or so ago after using it on my orchids - with the orchids I have had very good results.
