Photone

PAR Meters are expensive($300-$500), so I’m using the next best thing, a $5 app. Photone

While its not on par with an actual quantum meter, Shane from Migro thinks its acceptable for the hobbyist. Migro Review

My Lights

• The Timber 3vl, in the 2x4
  • Store Page
• The Spider Farmer SF-1000, in the 2x2
  • Migro Par Test

Grow Environment

Trying to take VPD into consideration these days. Pulse has some great information on VPD here

Stage	RH	Temp
Veg	40-60%	70-85F
Flower	40-50%	65-80F

Water

• I don’t check regularly, but its usually around 6.4 out of the tap.
• In the 2x2 I have 2 Blumat carrots with their Blusoak tape connecting them in a 30 gallon Grassroots Living Soil Pot
• In the 2x4 I have 3 carrots (1 per pot/plant) with 4 drippers each in 10 gallon Grassroots Living Soil Pots

Moisture Meter

Recently picked up the Blumat digital moisture meter for the 30gal so I can dial in my irrigation. I plan to eventually get a cheaper reotemp meter and calibrate it to the 30gal and use that for the 10gals and house plants.

Condition	Measure (Mbar)
Saturated, very moist to moist	10-40
Moist to moderately moist	50-120 (target zone)
Dry to severely desiccated, irrigate range	120-190
Dry - Irrigation Urgently Necessary	200-300

Feeding

Loosely following the “BuildaSoil Way”

• The write up is here

Low Stress Training

• Currently have a bamboo trellis set up in the 2x2, I’ve been enjoying it more than the clip and tie down method. Its made keeping the canopy even(ish) much easier

Trellis

The trellis is made from 4 foot bamboo stakes cut down to 2 ft and lashed together with soft garden wire to create two 16 cell grids. One is about 6” above the pot and the second is another 6” above that.

As the plants grow I tucked the tops under the bamboo to encourage side growth to grow to create an even canopy about 8” under the light.

Defoliation

I’ve been terrified to defoliate more than a few leaves at a time in flower. I know I need to be better about it, especially in the 2x2 where space is limited. These are some videos I’ve seen that have helped me.

• Rasta Jeff suggests taking off any leaves that have a purple petioles(stems). He thinks if the petioles has gone purple its been around long enough and is safe to remove.
  • Grow From The Heart #732: Defoliation
• Guru mentions that older leaves are less efficient at photosynthesis than newer/younger growth.
  • Dude Grows: Leaf Stripping

Drying

• 60/60/16
  • 60 Degrees
  • 60 % RH
  • 16 Days
• Buds should feel “crispy” and stems should snap when bent
• I’ve had success moving the plants to a yellow top bin for the last few days to help preserve the ideal drying conditions longer.

Curring

• Burp jars a few times daily during the first week
• Once environment settles you only need to burp every few days

Post Processing

Dry Sift

• Dry sifting is best done in cool temps, 60f or lower
• Most glands are 75-125 microns in diameter.
