Description
No Mercy CO2 Tabs are tablets that release CO2 into your feed water, giving your plants extra carbon dioxide at the roots without an expensive CO2 system. No Mercy blends them with directly absorbable magnesium sulphate to help prevent magnesium shortages as growth speeds up.
Why growers use it
- Extra CO2 for healthy plants, without bottles or burners
- Useful in poorly ventilated rooms, which can run short of CO2
- Added magnesium sulphate
- Easy: drop a tab in your water tank
How to use
Use 1 tab per 100 litres of water, half an hour before watering, at least twice a week. Only use on healthy plants. Plants don't take up CO2 in the dark, so don't add the tabs shortly before lights off; No Mercy says the CO2 stays in the water for about 4 to 6 hours. Your pH may dip slightly for a while.
Sizes: 60 tabs and 150 tabs.
