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

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 |
Loosely following the “BuildaSoil Way”
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.
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.
