Anyone use the new STG or Sure to grow cubes? Supposedly a superior alternative to coco and rockwool. Not sure what they are made of but they look white like cotton. Just curious if any rockwool users have switched over or compared the 2.

What STG says about itself:

STG Advantages for Growers:

Compatible with major growing systems
Light, clean and hygienic
Requires no presoaking, no pre-conditioning
Does not interfere with nutrient solution EC and pH
No mess, no clean-up, no measuring
Indefinite shelf life
Lower product cost, lower freight cost


STG Advantages for Plants:
Quicker germination and higher yields
Optimal aeration and water retention
Inert, sterile and pH neutral
No nutrient salt build-up
Less incidence of disease, molds and fungus
