FRESH DELIVERY, so come and get your Co2 producing Breath Bags Today

Co2 Producing Breath Bags have taken the indoor gardening world by storm! They create an increase in available Co2 for up to 6 months requiring no gas refills or expensive dosing equipment and ongoing expenses!

Locally supplied by one of Australia’s largest professional mushroom cultivators these are fresh and alive and have a longer life than other imported competitors which may already be many months old!

Aussie Co2 bags are great to use for all stages of propagation, vegetative growth, and flowering. Simply hang your bags just above the plant canopy if using a sealed room or timed extraction. Or simply place down under your plants and let the negative pressure and extractor fans pull extra co2 up through the canopy.

Suitable for all stages of growth (propagation, vegetative, and bloom)

Green Diamond is different to other base nutrients

Green Diamond contains a Bio Mineral Suspension that includes organic metabolites, Fulvic and Humic acid as well as a mix of vitamins for faster growth.

Designed for high performance Hydroponic and Coco Fibre systems, Green Diamond contains natural chelates (which boost uptake) and the highest quality, pure minerals.

Green Diamond also contains additional trace elements, B Vitamins and Bio Stimulants to produce a powerful Bio Fused nutrient, complete in all micro and macro minerals needed for healthy plant production in hydroponic mediums.

Many brands recommend the same rate through all growth stages but a plant should not be fed the same amount of each element through the different stages of growth and bloom. The Bio Diesel Nutrient Program has been designed for growers who want simplicity and the ability to control and “dial in” their nutrient solution according to the plants needs.
