Las Alpujarras @ 15 days flower ~ ‘simultaneously monoecious’

August 3, 2012

Back on 07/17 I decided it was time to induce flowering in these plants. I shortened the day length to 12 hours and fed with the Peters 10-30-20 @ 100PPM N. The plants have grown considerably since then. Unfortunately all of the Las Alpujarras displayed both male and female flowers at the same time. Plants […]

Las Alpujarras @ 42 days ~ Rapid Vegetative Growth

July 17, 2012

It’s been twelve days since I transplanted these up to #10 nursery containers. From the beginning these plants have received plenty of water, the correct type and amount of fertilizer and 16 hours daily of cool-spectrum T5 fluorescent light. My room temperatures stay in the mid 70’s and the plants are constantly swept with an […]

Las Alpujarras @ 30 days ~ Shock-Free Transplanting

It’s been thirty days since planting and now it’s time to transplant these seedlings. The relative shape of the plants can be clearly seen at this stage.

Simple and Reliable Flood and Drain Setup

July 5, 2012

A simple flood and drain setup was exactly the solution I needed. Setting up these systems is really simple. The […]

Method Seven Protective Eyewear ~ Protection and True Color Under HPS Lighting

June 28, 2012

I had read about these glasses from Method Seven some time ago and thought that they sounded like a good idea. If you have spent any time at all in a cultivation facility you know that the light from high-pressure sodium bulbs – HPS – is extremely red and renders colors poorly. What you may […]

Alpujarras Update @ 16 Days ~ Second Set of True Leaves

June 21, 2012

These have all put on their second set of true leaves, the shape of which might suggest some things about their character. The leaves on the Haze seedlings, those in the orange tape, are generally long and pinnate. There is a clear space between each leaflet where they are attached at the petiole. As a […]

High Density Propagation Bench Project

June 15, 2012

I have a consulting client that owns and operates a busy MMC in Denver. He came to me looking for ideas to increase his yield. One area where I saw room for significant improvement was his propagation bench. His planting density is just over 2 cuttings per square foot. This was due in large part […]

Alpujarras Update @ 9 Days ~ Seed-to-Seedling

June 14, 2012

It’s always a bit of a thrill to see seeds break through the soil. Witnessing things grow, to me, is a very powerful affirmation of life and of living. This group of plants has had an almost perfect entry into the world. They’re fresh and green and healthy. Here are some pics I took early […]
