Hey guys! Sorry for the long waiting review on the lamps !
But I ended up in a lot of private problems, so I needed some time off the forum..
nevertheless!
Lumatek Attis 300W
After my judgment it’s clearly the winner of the grow. Why?
It makes literally no sound at all.
Faster and bigger veg grow, even though it uses less watt than the viper.
easy to clean.
Choices to dimm the light from 20-40-60-80-100 %
Better spread of the light, it reaches a bigger area.
Same size buds all over both lamps - which is good when it used less energy than the viparspectra.
Perfect light for seedlings also, or clones with the dimm option down to 20% of light.
Viparspectra R900.
good beginner light. The price for this lamp and what it can do is good, honestly.
very hard to clean
should could replace a HPS 600W - which I think it clearly don’t do.
not enough spread of light.
Makes a lot of noise with the build in fans.
More easy to “burn†the plants than with the lumatek.
Half the price than the Lumatek which I think it’s a good beginner lamp no doubt.
my conclusion is
it seems the plants like the lumatek light much more than the blue/purple/red spectrum from the vipar.
the new plants is in week 2 now and again the lumatek plants are way bigger and growing way faster.
which I why I think the lumatek is the winner.
totalt yield for the grow was 388 grams. 12 grams from my goal.
happy growing captain !
