Dr Greenthumbs FAQ's
You pay less to move and store them. A liquid bottle is mostly water, and that water still has to be shipped and stacked. A dry pack is cheaper to freight, takes far less space and lasts a long time if it stays sealed. The cost is at mix time: you need a scale and you have to dissolve the powder fully before you feed.
Root Roids is the root-zone inoculant, sold in 75g and 225g. Like any inoculant it only works when it touches root tissue, so put it in the planting hole or against the root ball — broadcasting it on the surface of the medium does little. Root Roid Boost is the 500g support product for the same part of the cycle.
Go & Grow is the vegetative dry base; Bud & Bloom is the flowering one. Both bags are 1.5kg. Weigh the amount, dissolve it completely in water, then feed — never scoop and never tip undissolved powder into a line. Change from Go & Grow to Bud & Bloom when the plant enters flower. The two together cover a full cycle.
For dry nutrients, yes in practice. Guessing a scoop of powder gives you a different feed strength every cycle, and that wastes the point of a dry concentrate. A scale that reads to a gram is enough for these base nutrients; finer resolutions live on our digital scales collection if you want them.
Fruit Roids is aimed at flowering and fruiting, in 100g and 225g. It is a dry format like the rest of the range, so weigh it and dissolve it rather than guessing. Use it with the Bud & Bloom base — it does not replace that feed — and start it once the plant leaves vegetative growth.
