It is exactly the same product as the "Bloom Spectrum" one, but with some extra Blue. Lumens emission is lower than the "grow-bloom extreme", less gas inside, more economic.
We think it has a market because many small growers use autoflowering genetics, that are usually small plants, easy to spray with light.
The price of the "autoflowering" is lower than the "bloom". The reason is simply because we decided to earn less and use this products as a promotional pushing for all the Phytolite range.
