100% success rate with these seeds, and a great strain! I tried some seeds from another distributor, and they were all duds. Had a few of these left over, from a few years ago and they grew long tap roots in one day! Very happy with the quality of seeds at the seed pharm.

Ratio 1:30 CBD seeds are named for their chemistry. The figures in the name are the balance of THC to CBD, about one to thirty, and the strain label puts THC at just 1%. For growers who want a CBD crop with as little THC as possible, it is one of the clearest choices in our range.
Aroma
The nose is earthy and piney with a gentle spice. As the buds cure, woody and herbal notes come through. It is a quieter smell than most THC strains, though a drying room still needs ventilation.

How to grow Ratio 1:30
It is straightforward to grow. The plant reaches a medium 100 to 150 cm on the strain label and branches evenly, so a single topping and a few ties are enough to keep a flat canopy.
Light is what it wants most. Indoors, give it a strong light and keep the canopy at an even distance from it. Outdoors, choose the sunniest spot you have. Feed moderately and let the pot dry a little between waterings.
The buds set firm and fairly compact, so thin the leaves in the middle of the plant once flowers start and keep humidity down near harvest. It needs 8 to 10 weeks to flower. Grown outside in a sunny bed, expect about 500 g per plant.
