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
  • Timber has since re-branded to HighGrove and discontinued this light
• 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 2x4 I have 2 carrots and 3 feet of drip tape in one 30 gal and in the other I have 3 carrots with 4 drippers each.
  • I’ll likely be replacing the drippers with drip tape, eventually.

Moisture Meter

Condition	Measure (Mbar)
Saturated, very moist to moist	10-40
Living Soil Target Zone	50-80
Moist to moderately moist	50-120
Dry to severely desiccated, irrigate range	120-190
Dry - Irrigation Urgently Necessary	200-300

BuildASoil recently started selling Blumats and recommend aiming for 50-80 in living Soil video link

Feeding

Loosely following the “BuildaSoil Way” with some BIO-AG products mixed in.

Low Stress Training

Trellis

I have a re-usable AC Infinity trellis in the 2x4.

As the plants grow I tucked the tops under the net to encourage side growth to grow to create an even canopy about 12” 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 these smaller tents 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

Curring

• If you nail the dry, you won’t need to burp at all
• 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.
