FREQUENTLY ASKED QUESTIONS (FAQs)
WHO SHOULD USE SURE TO GROW®
Who should consider using Sure to Grow®?
Sure To Grow® should be considered by any
hydroponic grower who uses a medium to do any indoor
gardening. Sure To Grow® is particularly advantageous for
growers of high turnover crops like herbs, baby greens,
sprouts, wheat grass and microgreens. Growers of large crops
like tomatoes, cucumbers, peppers and lettuce will see great
advantages with our STG Grow Cubes, Blocks and Slabs.
Do you need to be a hydroponic grower to
use Sure to Grow?
While Sure To Grow® is especially well
suited for hydroponic applications, conventional growers can
use it with some minor modifications to their fertigation
regimen. Sure to Grow® Loose Fill can be added
to soilless nursery mix up to 50% with no modification to
growing practices.
Can I use Sure To Grow® in all types of
hydroponic systems (Drip, Ebb & Grow, Flow)?
STG is compatible with most hydroponic
systems including flood and drain, Ebb and Gro, NFT, drip,
deep flow and float.
Can I use Sure To Grow® in my cloner?
STG cubes are excellent for rooting
cuttings. When cuttings are rooted in STG instead of the
more traditional Neoprene plugs there is less damage to
roots and less shock upon transplant into the growing
system.
Does Sure To Grow® have a product for
Certified Organic Growers?
In order to satisfy our many growers who
grow organic crops, we will introduce an additional line of
STG that will be made from Lyocell, an organic, sustainable,
cellulous fiber. This fiber is in-soil degradable and may
conform to OMRI guidelines for use as an organic medium.
