Product Spotlight - Baseline

If there is one liquid ingredient worth having around, it’s baseline. Baseline is:

A soluble liquid supplement that feeds beneficial microorganisms; an excellent source of humic and fulvic acids.

It can be used in conjunction with an existing organic or synthetic liquid fertilizer program. It:

•Increases nutrient cycling

•Is an excellent ingredient in compost tea

•Can be used as a stand-alone foliar spray or root drench

•Can be used in drip irrigation systems without clogging emitters

While more expensive than other powdered humics, baseline has many benefits. First off, it is of the highest quality humus and will not create nutrient deficiencies, lockouts or other irregularities sometimes observed with powdered humics. Additionally, its liquid nature makes for rapid tank mixing, unlike other humic powders that get caked onto tank sidewalls and congeal into black clay like dots all over your equipment.

Baseline is basically like plasma for your plants and is a key component to the health of mother plants or any plants that spend many months root bound in containers. Root bound plants can be continuously regenerated by weekly applications of baseline and other microbial products.

Here is a short vimeo video demonstrating the use of baseline in a small nursery in Humboldt County:


Compost Tea Feeding Schedules

Compost tea can be an effective strategy for balancing feeding schedules. But in the case of compost tea, more is not necessarily better. In fact, over application can actually cause significant soil imbalances. Many times, the problem of over-application of compost tea becomes compounded when the soil remains over-saturated for too long after the application of compost tea, especially if it is being used at every watering. If the microbes have a big boom cycle but then the soil is water logged, the bust cycle will lead to a much quicker anaerobic state, which can lead to a number of different problems.

There are many instances where compost tea is only applied 1x month to outdoor plants with excellent results. Just because you are seeing excellent results with compost tea, doesn’t mean that adding more will work even better.

Feeding Schedules for Rapid Growth

  1. Liquid Fertilizer

  2. Compost Tea

  3. Water

A very successful regime observed in Humboldt County involves transitioning between liquid fertilizers, compost teas and watering.  So one would use their liquid fertilizer on the first watering, the second watering would be the compost tea and the third watering would be plain water. Depending on site specific conditions, you may want to repeat that schedule or mix and match in different patterns. Some growers dilute the tea and some apply it as full strength. Sometimes they mix it with liquid fertilizers. Some growers pre-amend their soils with organic fertilizers and then simply use compost tea periodically (~1x-2x month) throughout the growing cycles.

Whatever methods you decide to choose, know the backbone to any good compost tea is:

  • Compost/Humus

  • Worm Castings

All the additional ingredients you add will depend on your knowledge of the plants life-cycle and current soil biology. There are ways to brew grow teas, bloom teas, high bacterial teas, high protozoa teas and fungal teas. People use molasses, fish hydrolysate, frass, alfalfa, glacial rock, kelp, straw and many other ingredients, but the backbone always starts with a HIGH QUALITY compost or castings.

Calcium's role in Cannabis Physiology

Calcium's role in Cannabis Physiology

"Calcium is an extremely important plant nutrient due to its many functions, which includes membrane structural integrity, maintenance of homeostasis, segregation of genetic material during cell division, gene expression, energetics and enzyme activities. The full picture of calcium-mediated physiological processes has not been fully described here nor clarified in academic research; however, researchers do know that calcium is immobile in plants and that it is a constant requirement throughout all growth phases."
