How?
I planted a seed in soil. It germinated and started growing. I gave it water, light, food, and air. That's all I did.
I used no cannabis specific products. I used the same knowledge I use to grow vegetables, flowers, houseplant, orchids, etc... And I used the same products as food. Calcium nitrate, a micronutrient blend, monopotassium phosphate, magnesium sulfate. All of which I use to mix up different blends of nutrients for different plants. But typically most plants just require a balanced feed like 4-4-4 or 10-10-10. Including cannabis.
And over feeding is bad for any plant. I think I might have gotten too aggressive on the feeding with this one. But being a pure sativa and the small container it's hard to get things just right. Overall I think it is doing great considering. But just transplanted in to a two gallon pot of 70% Happy Frog and 30% Ocean Forest.
