SG15's 2kw Flood & Drain Perpetual - PE, NLxS, Sour Kush, PPP
Welcome. Last round was a bit of a bust for me with some temperature issues so I'm back at it again. This time I'm also armed with 2 scrog screens and temperature monitoring in (1)flower space (2)canopy temp probe (3)root zone and (4)rez. Hopefully keeping a watchful eye on all those parameters can help me avoid the same set backs I experienced last round. This will be my 11th round of flowering, so looking forward to applying more knowledge learned. I was also able to purchase a 4x4 table to use for veg and that has helped the quality/lushness of my veggies immensely. Hand watering hydro is very difficult because you need to excessively water to keep the root zone EC from spiking in the pots. And just measuring runoff is a bit of a guessing game... Anyhow here's the setup rundown & pics. Hope you enjoy the show!
Strains: 5xG13 Labs Pineapple Express 3xWOS Northern Lights x Skunk 5xRP Sour Kush aka Headband and 2xNirvana Pure Power Plant
Medium: Clones in Root Riot cubes. Then into 50% Hydroton, 50% rockwool grow chunks in 2 gal Smart Pots
Growing style: Flood & Drain
Methods: Topping, lollipop week 1 & 2 of flower, Scrog (2in and 3in squares)
Base Water: City tap, EC 0.3-0.4 mS, Ph 8.6
Nutes: full House & Garden lineup
Additives: ProTekt, Great White Mycorrhizae (veg only), Fulvic Acid, SM-90, Roots Excelerator
pH: 5.6 to 6.0, using GH Ph Down
EC: Starting .7 mS working up to 2.2 mS
Reservoir size(s): 30 gal rubbermaid filled to 25 with nutrient solution for the 3x3, 50 gal Botanicare EZ-Drain filled to 40 for the (2) 2x4 trays
Flood volume: 15 gals for 3x3, 25 gals for (2) 2x4
Feeding schedule: 6x floods a day. Foliar Feeding flower weeks 1 & 2 with SM-90 & Fulvic Acid.
Lights: 2x1000W Hortilux HPS flower & 2x4ft 8 tube t5 6500k for veg
Light Schedule: Veg/clone - 18/6; Flower - 12/12
Temps: 83-86 degrees f lights on; 73 degrees lights off. (C02 makes this temp acceptable)
Humidity: 35-55%, make best effort to keep flowering below 50
Circulation: 16" Air King wall mounted fan on low/oscillating, Box fan on low, 449 CFM Vortex 6" lights + exhaust + scrubbing
Odor Control: Phresh filter 6x24" 550 CFM
Size of grow rooms: Veg/clone room - 6' x 5' x 6' space; Hydro Flower room - 5' x 8' x 8' (320 cubic ft. of space) poly walled
How long Veg'd: 6 weeks or 18"
Sour Kush bud (pheno 2) after a long flush
Top is canopy temp, bottom root zone temp
Gotta have the CO2!
One dirty ass tray left to clean
Bio Green Clean to the rescue lol
plants movin into their new homes
Lollid the bottom 6-8"
4x4 tray with 3"x3" holed screen
3x3 tray with 2"x2" holed screen
Should be set to explode... questions, comments, concerns, hell even on-topic rambling is fine here. Let the games begin!

Yea buddy! It has begun and I have the first seat!! Sick strain selection, bad ass setup and a legit grower! I'm jealous .
Hell yess! This should be a sick thread, awesome show here.
looks good someguy15..are you useing the one gal jugs to rise water level?
lol thanks my friend. You have all the knowledge you need, just need some space to bring those ideas to fruit. Your last screen was really good lookin, I'll be watchin this next screen play of yours lol

If you don't have time to collect jugs, Ziplock brand galon size freezer bags work pretty well too. Fill them with plain water incase a seal goes...then it's just a little top off lol

A floor drain would be heaven indeed. I'm actually trying to minimize runoff as much as possible.
It takes a lot more precision in regards to EC and pH but it saves a decent amount of time and money.
I get a little bit here and there just running on to the poly floor I have down which is no big deal, just clean
it up after. Enjoy the vacation.

Damn stretch always has my ph going wack, they stabilize like a rock by the second or third week tho. Gonna need a IP cam just to put myself at ease while I'm away lol

Just been training the SK1 which is a stretchy bitch, but amazing sativa high. Only downsides she doesn't smell nearly as good as SK2 or yield as much. But for now I'm keeping both cuts around as I enjoy both in their own way. The NLxS are just now reaching the screen and the PE's aren't far behind, maybe 1" below or less on average. PPP's are the shortest about 2.5 inches below the screen but this is good as I know she likes to stretch every bit of 3 weeks. No deficiencies or bleaching noted anywhere. Lights currently 24" from screens.
Root zone temps have ranged from 65 (night) - 74 (day) which is acceptable I believe. I read a great soybean study about root zone temps and yield here if anyone is interested. The basic conclusion was 77 was optimal, 86 at max and 68 at min. The study held the root zone at a constant temp tho, which isn't 100% accurate naturally as it will fluctuate. If anyone has any experience with root zone temps and cannibus I would appreciate a bit of guidance here. Never a parameter I had to worry about in closets but my environment has changed a lot now.
Canopy temps were 70 (night) to 83 (day) which I'm happy with for now. Probably bump that up a touch when the CO2 starts crankin in week 2.

I think I saw this on Reddit the other day.
