Wow. How does the upper part look like? It has to be massive! Weight?
The tent has 2 Gorilla Glue autos - Wilma (Rudolph) and Chris (Evert) in day 85.
The light in the from is a Viper Spectra XS-1500 that I bought for the last grow when I had one Gelato auto that was about 2' tall and another Gelato ("Jeff") that was > 4'. I tried lighting both with my main light but gave up and bought the 1500. I referred to those plants as "Twins", after the movie with DeVito and Schwarzeneger. The 1500 is the "sidecar" light that I need because the branches (that's two branches from Chris) could not fit in the tent.
Wilma got off to a slow start - her seed pod would not detach. She's smaller than Chris but, interestingly, she flowered a few days before Chris. My journal reads "First flowers" on day 48 so Chris flowered ≈ day 50.
Don't know what the weight will be but I'm thinking it will be "sufficient".
I'm growing in a SuperPonics 12 XL - yeh, I tithed to the SuperCloset God when I did a grow in 2017. That grow got wiped out by a power outage - thank you Southern California Edison - so I archived my grow tent until early last year. It was neat to fire up a Kind blurple (that went in the trash can about 5 minutes after I got the PAR map from Kind).
There are about 20 colas between the two plants. Chris is ≈ 50% larger than Wilma.
This thread has been really helpful to me, BTW. It forced me to go back and re-read some documentation and I rewatched a couple of De Bacco University videos on lighting. I've been hesitant to go over 50 mols and that's not easy because the "front row" of colas is right under the front bar on the X3. I've used a piece of parachute cord to move them forward and backward, in and out of the light cast. When it's under the light, PPFD is 900+; loosen the cord and the fall forward and PPFD drops to 600's.
I measure light using my Apogee. I sample 20± colas and then drop it into my Excel journal.
256 - wattage (a Growcraft X3 at about 14")
18 - lights on hours
# - sequence number
Numbers at the bottom - standard deviation of PPFD, average PPFD of plants > = 35 mols, average DLI of plants > = 35 mols, standard deviation of PPFD. These values include only readings of >= 35 mols.
The % numbers are the percentage of colas in a given light band.
This looks a little OC, no arguing that, but it does let me know what's going on with light in the tent. The biggest issue that I'm not giving them enough light. That's what I concluded after watching DeBacco last night. Per his video - and he's on track with Bugbee and others - is that cannabis, non-CO2, should get up to 65 mols using 24/0 and 58 mols using 18/6 (just noticed that he spelled "mols" wrong - interesting…)
