BuildASoil Grow Journal #1: The Setup July 27 2016, 5 Comments

Journal #1: The Setup and Seed Sprouting

This blog goes overboard with everything you would ever need to start a premium at home indoor grow. Follow along for the key details. 

BuildASoil Grow Journal #1 from BuildASoil on Vimeo

Hello and welcome to the first Grow Journal! I am Jeremy Silva and the founder of BuildASoil and growing plants is my passion. That passion led me to building soil that spoiles them. Lately I've been in the office and on the phones a little too much and this Journal is the results of a goal I have to spend more quality time in the garden. I've had a lot of changes in my personal life over the last year and that has changed the location of my garden. That being said I think this is a perfect opportunity to highlight what it actually takes to start a high quality and low budget home grow. Instead of making it appear really cheap and only mentioning how much it costs to make your own soil, I figured I would highlight the absolute most expensive way to do this, which is to purchase everything brand new all at once including all the little details. 

This Grow will highlight what any average home grower should be able to do on thier own using minimal plant numbers and a fully organic approach.

We’ve had an overwhelming response to our grow videos and blog content but realize that we need to put a complete grow together from start to finish to help our friends understand some of the basic principles. This grow journal will highlight our BuildASoil style of indoor cultivation starting from seed through harvest. Instead of attempting to teach every variable we will show you a basic home setup and discuss the principles that make this all work. If you have specific questions, please leave them below and I’ll do my best to answer them directly.

The Grow Setup: (Getting the environment right is imperative)

Keep in mind many of the expenses below are not neccessary and are one time costs that you could easily save by buying used or getting creative. 


Boneyard Seeds and Verified Genetics

#1: Truth Tree by Boneyard Seeds Norcal (Mandelbrot VIII x Redwood Kush)

#2: Ektoplasm by Verified Genetics (Ghost OG x Bazooka Bumble)

I'm honored to have these packs and will be sprouting 6 Seeds From Each pack due to limited Plant Numbers. 

This setup will be for twice what the average grower will use because I'll be comparing two different growing styles. Geo Pots vs. Earthbox Sub Irrigated Planters. I'll be vegging and flowering in two seperate 4x4 tents. 

Veg Room: 

4x4 Grow Tent : $174.95

150w Endomaxx Grow Light: $350.00

DuraBreeze Orbital Wall Fan 12": $51.95

DuraBreeze 6" Ducting 25': $18.00

DuraBreeze Duct Defender: $10.50

2 Gallon Geo Pot Velcro Transplanters x 6: $30.00

With both tester tents running the cost will be double which you may want to consider if you are going to be growing perpetually with one dedicated veg tent and one dedicated flower tent. For this grow we will be vegging and flowering in the same spot without moving to a separate flower tent.

Basic Seed Sprouting Info:

1. Good Seeds

2. Good Soil

3. Plant the seeds about 1/4" deep. Place seeds sideways in hole and then cover with soil and tamp lightly to make sure the seed won't move once watered. 

4. Cover with mulch of some sort and keep the top of the soil moist. 

5. Avoid temperature extremes and if possible consult VPD charts for Humidity vs. Temperature ideals.

Oly Mountain Compost: Extensive Herbicide, Heavy Metal and Pathogen Testing Results June 22 2016, 2 Comments

BuildASoil's goal is to create an outstanding reputation for transparency with regards to our recipes, ingredients and Methods. It is in this spirit that we are sharing this extensive report with you.

Attached here is the PDF: Click Here

Notes from testing:

We did not detect any herbicide, insecticide, or fungicide compounds in your sample. When you see the result as < the MDL this is a non-detect.

The MDL is the method detection limit. This is as low as we can see on our instrument with certainty. Anything below this is a non-detect.

We also did not detect an fecal coliform in your sample. This was also below the detection limit. The salmonella test was negative.

You did have yeast and mold in the sample. (As any good compost should) We do not normally test for yeast and mold in the compost samples. (We tested because we wanted to know) They are also not required by the EPA as far as I know so I do not have any regulatory information on yeast and mold.

I included the EPA Compost Quality Standards for Class II Composting Facilities for your reference. It looks like all of the heavy metals tested are well below these standards.
