Planning on flip today - we still need to deal with Topping and sufficient start height.

- We’re attempting to assure we ONLY use low sediment inputs (clean lines). ONLY Low/Non-Precipitating inputs . . .
Messed up initial mix, Only achieving EC 1.5/No Change … ok for a day or two . . .
1100 - Ran total of 320 sec. 320/2.16: ~ 148 ml
@220 sec per fertigation, we should be delivering ~92 ml/event
Or 368/plant/day.
This implies
- Deliverered to Tent: 2944/day
- 10% Runoff: 294/day
We’ll be looking for ~300 ml runoff @ Lights on @ 1900
- [ ] ADJUST Fertigation Duration to achieve
294 ml/day

I’m pretty much sure we’re delivering significantly less Fertigation than we think. Ran pump for a FULL 9 Minutes at noon. There has been no runoff, and plants are not terribly happy. I think we’re severely under watering.
Solution - Buy pump with advertised 6’ HEAD,, 35 Watt SICCE Syncra 2.0.
- [x] Order SICCE Syncra 2.0 from Amazon
- [x] Order 3/4” NPT Male to 3/8” Barb
Fertigation Observations
We need to be able to irrigate in minutes per event, NOT 10’s of minutes. The Little GIANT transfer pump LACKS sufficient HEAD to consistently deliver across the irrigation rings. The new pump should be able to provide sufficient pressure to do . . .
Pressure (psi) = .433 * Height (ft)
Alternatively
2.31 ft/psi
The Syncra 2.0 has a 6.5’ Head, delivering ~ 2.8 psi, 10% of the max flow at the manifold, meaning the pressure restrictor, won’t.
Ex.
- If we Deliver @4ft, we have (2.8 - 4(.4333)) or 2.8 - 1.7 or 1.1psi
IFF We’re not getting decent flow, will have to RAISE TANK 2.3 Ft to achieve 2.0 psi or more …

ONCE WATERING IS RESOLVED and we have obvious Vegetative growth . . .

- [ ] FLIP TO FLOWER: Drop Intervening Dark Hour (Tent Light Controller)

Removed Pressure Restrictor from XeriBird8 Manifold and cleaned well.
Replaced Little Giant pump with SICCE Syncra 2.0 (6.5’ head). The little giant was probably fine . . .

KEY Problems were the back flow protector on the Little Giant that reduced flow 1PSI, and flow restrictor on Xeribird8 for 10x the pressure of our little system. We’re lucky to have a couple of PSI at the emitters. That said - we produced ~1.5 gallons of runoff yesterday. To maintain runoff (but less than 1 GAL!), I’ve HALVED delivery times. Goal is to reduce runoff to ~10% of estimated delivery …
Current Fertigation Run: 5 min Duration, 4 times in 11 hours.


We’ll FLIP on Week Change - give a couple of days for root development, some more height.
We need to
- [ ] Would like to grow to middle bar of tent BEFORE topping.
- [ ] VERIFY ROOT POPULATION AT BOTTOM OF CONTAINERS BEFORE FLIP. (If we’re well populated, we’ll rock - delay FLIP UNTIL All containers need to demonstrate significant root development around periphery of the bottom of each airpot.

Runoff: [ 700, ml], [ 1.0, mS]
During Dark - Flushed RLA CalMag Fuel, ~ 450 ml/plant @ EC: 1.8 mS
- I’m not convinced I properly buffered the coco. Will do this weekly if Coco induced Calcium deficiency observed.
