any results after a month?I'm not sure whether I should put this on hardware section or plant section. The question is about US fissiden but related to the lighting.
Anyway I got three 2ft tank same size, All of them with 55W PL light (MAGNUM II). Two of the with OSRAM Delux L 55W/860 light bulb and one with SAFER... 55W/870 light bulb (can't really remember the brand). I follow EI dosing regime with the same amount of fert to all of them.
The question I would like to ask is why my US fissiden grow nicer, denser on 55W/860? Even the newly tied US fissiden start to grow nicer under OSRAM light bulb. Is it because of OSRAM lightbulb having more red spectrum that plant need? or is it because of the color temperature? Where can I get the OSRAM light spectrum info? I’m currently swapping the light bulb and see if the grows improve after 1 month under OSRAM light.
