Should I try KLN instead of Superthrive?

[Nengco]

Have you guys use k-l-n and clonex root solution?

I used to use K-L-N regularly. It contains synthetic auxins, IBA and NAA. (Superthrive contains one of them...I think it's NAA). If fresh (the synthetic hormones degrade fairly rapidly), it can be a powerful root-growth stimulant, but there is the risk of overdosing it, leading to flower deformities.

Clonex is a very dilute fertilizer that has thiamine (vitamin B1) added. B1 has been shown to have some stimulant effects, but it's really not all that powerful.

If you want a truly remarkable, yet safe stimulant, consider KelpMax.

I've used KLN and SuperThrive in the past. Got some deformities using SuperThrive (probably wasn't measuring it well). KLN didn't do much for me. Been using KelpMax for quite some time, and still do.

I use ST every 45 days... A shoot once in a while. Beside that it will no be good ..the plants get use to it or end up having the opposite effect.
