Cannabis seed genetic testing

Plant & Cannabis DNA Testing

Genetic testing allows you to glimpse into the genetics of a plant long before you’re able to observe what they actually will look like.

A small amount of DNA collected from a leaf makes cultivation more efficient by saving you time, electricity, water, labor, and ultimately your wallet.

​Get ready to unlock the full potential of your harvest!

Outgrow The Competition

SAVE TIME ON PLANTS YOU’RE GOING TO CULL

DNA testing can identify male plants months in advance, or powdery mildew infected plants weeks in advance.

SAVE MONEY COMPARED TO VISUAL IDENTIFICATION

The time and space saved by DNA testing also reduce the amount of electricity, water, nutrients and other resources.

MAXIMIZE YOUR AVAILABLE CROP SPACE

Early identification of plants to be culled frees up space while plants are still young which enables more efficient staggering of crop cycles.

ENSURE PLANTS ARE FREE OF PESTS & DISEASE

Powdery mildew and fungal contaminant screening eliminate worries about crop loss as you approach harvest.

Leading Innovation In Plant Genetics

​​We use the most sensitive DNA detection method available, quantitative PCR (qPCR), to identify specific genetic targets without revealing the exact underlying DNA sequence. With no restrictions on order size – we support cultivators of all types.

Go Beyond The Lab

Cannabis Hermaphrodites – Which Sex Carries the Hermaphrodite Trait?

To the best of my knowledge, cannabis hermaphrodites are genetic females, by definition (two X chromosomes). We at Delta Leaf have never seen nor heard of a genetically confirmed Male plant that ended up developing female flowers. Does this mean the hermaphroditic trait – or the genetic tendency for an individual plant to develop both male & female flowers – can only be passed on by the mother?

The Ultimate Guide To Pheno-Hunting

Cannabis is an amazing plant for a wide variety of reasons. However, it’s the genetic diversity of cannabis as a species that truly sets it apart from most of the other crops that are grown and cultivated by humans. Be sure to leave us a comment after reading through.

Why DNA Sex/Gender Testing Is A Game-Changer In Cannabis Cultivation

Plant DNA Sex/Gender Testing Delta Leaf does many things well, including offering cannabis growers an innovative method of DNA testing that lets them know whether their plants are male or female months before sex could be determined by traditional methods.
