GIB CO2 Tabs Extra Slow

Only healthy plants will be able to effectively use this extra input. During extensive testing we perceived as the possible side affect a shortage of magnesium due to the high speed of growth. To effectively prevent this we have added 1.2% magnesium sulfate. The tabs release the CO2 in the water and thus stimulate the growth. Healthy cannabisplants can absorb many times more of this important nutrient CO2 as is available in the air. 60pc.
