After five autoflower grows, I've decided to do a photoperiod grow, one of the main reasons being that I can have some influence on plant size by controlling when to flip to flower. In contrast, autos grow how they damned well please and I've ended up with plants all over the map with some plants nice and compact and while their tent mates have towered at 48" and taller. Enough of that. I'm looking forward to a nice, easy veg, flipping to flower, and then a clean, quick harvest.
Strain - Chemdog photoperiod, purchased from Nirvana in 8/21.
Number of Plants/Seeds - germinated two seeds, Charlie and Juliet. I want to fill the tent but I'm tired of "Twins" grows. My thinking is to cull one of the plants and, unless a catastrophe strikes, Charlie will be leaving the res.
Growth Stage - vegetative at 22 days above ground
Water source - RO
Indoor or Outdoor - indoor, unfinished garage in SoCal
Grow Type - DWC
Tent - 2' x 4' x 6' Gorilla tent with 2' extension
Hydro Setup - DWC
Reservoir - Superponics 12XL. Measures 40" x 23" x 14". 35 gals total, 28 gals usable. Will be filled to 1/2" from bottom of 3" net pots
Reservoir Temperature - 68° (Active Aqua chiller)
Nutes - Jacks 3-2-1 mixed IAW the current feed schedule at 3.79-2.52-0.99. Per the approach detailed by @Farside in his thread "Growing with Bloom Nutes", I'll be using the same mixture throughout. In addition to Jack's, I'm using a potassium silicate silica supplement and HydroGuard.
Grow Lights: Chilled Growcraft X2 veg 330 watt, Chilled Growcraft X3 flower 330 watt
I also have a Vipar Spectra XS-1500 and a Mars SP 3000 that have been needed for previous grows. I'll use those for supplemental lighting, if required.
Lighting Plan -
Seedling - 24/0 with PPFD of 200
Veg - 21/3 with as high a PPFD as plants will support.
Flower - 12/12 with as high a PPFD as plants will support
Light Meter - Apogee MQ-500 calibrated by Apogee 8/22
Tent Climate:
Temperature - temps have been below their climatic average for most of the past two years that I've been growing here in Southern California. We had a hot spell in September 2022 but for the past few months, it's been cool and wet. Temps for Jan, Feb, and March are highs in mid-60s, lows in mid-40's.
Garage floor temp under the tent is ≈ 72 due to crap SoCal suburban home construction. This helps ensure that tent temps rarely drop below the low high 60's.
The "wall mount space heater" heater has been running in the tent since the grow started so temps have been 77°±.
Sensors
PPFD - Apogee MQ-500, calibrated by Apogee 8/22
Air temperature - AC Infinity Controller 69 ("ACI" and "C69")
RH - C69
pH - Bluelab monitor in the res + Bluelab pH pen
EC - Bluelab monitor in the res + Bluelab EC pen when making nutes
VPD - C69
With the purchase of an adapter from ACI, I no longer have to babysit RH to control VPD. The C69 is set to control Hugh so as to keep VPD at 1.0. I set that up a couple of weeks ago and it working perfectly. The ACI humidifier is on order. One of the advantages of the ACI humidifier is that, when it's used with the C69, it has 10 levels of mist so it can be set to add RH very slowly or even continuously to the tent. ATM, the VPD is ranging from 1.1 to 0.9 on a two minute cycle. With the ACI humidifier, I'm hoping to smooth that out.
VPD values - seedling at 0.8, veg at 1.0, flower at 1.2-1.5
AC - Whynter 14000 BTU portable. I don't anticipate using the Whynter during this grow.
Dehumidifier - Waykar 4500 sq. ft. model. I don't anticipate using the Waykar during this grow.
Tent fans
ACI variable speed oscillating fan (still in box)
ACI variable speed fan
ACI 4" inline fan
Kasa Smart Strips are used to for scheduling or controlling power to all electrical devices in the tent.
Trellis - Scrog Pro 2' x 4' and ACI 2' x 4' net
Pests - I've had thrip infestations and will be spraying Spinosad prophylactically during this grow.
