I totally differ on this one.
I have noticed a difference on this crop using superthrive wether you say it works or not. There is NO doubt in my mind that the difference is down to ST, as this is the first time I have used it.
Yes it is for stressed plants, I can assure that my plants were never stressed in the first place. they had plenty of TLC and very little transportation.
The reccommendation with superthrive is that if you transport plants... then use this to get the stress out etc. however the plants i have at the moment ive been adding a few drops daily and they are the healthiest meaniest looking f**ckers i have grown(also absolutely beautiful....). I have got a couple of plants on the side without the ST and they just dont look as perked up at all.
Im going to sing the stuffs praises. So far im gonna continue using right through this crop to see the end result......
no doubt ill post back at christmas with the final score.
I say it makes a difference.. stessed or not!
