DONT! use Greenhouse long flowring powder

[Doctorgrinspoon]

quate:
"Our experts have just informed us that they recently encountered the same problem using Calcium + Long Flowering. '

theres an issue with their Calcium formula.
greenhouse informed me they will change the calcium formula, but untill they do-dont use it.
i personally lost faith in their product line-its been around for 4 years, and only now they found the problem?
not to mention they advice flowring landraces with 1.8 EC..seriously?
a better option is Bionova long flowring, at 50% dosing.
Peace

There is no calcium in the long flowering feed from Greenhouse.

The Calcium is another product. I think they are saying there is some issue with the combination of the two. Not sure what that issue is? Do you know? And if you are using tap water you don't need the calcium anyway in many places.

50% of the suggested dose seems to be pretty good irrespective of the brand. Depends on the amount of light and everything though.

Anyhow, that stuff is so in much overpriced. Just do a Google search for 18 12 18 fertilizer. Greenhouse feeding is selling a pound of that stuff for the price of a 25kg bag...
Just regular agriculture fertilizer as all of their salt based ferts. A giant rip-off.

Which one? I could only find Ferty 3 Mega from Haurt-Manna but the constituents are different (and seems to be sold out everywhere so I couldn't check the price).
