Update: Gas Lantern Routine - Week 4 completion
To recap the
Gas Lantern Routine; basically it uses 12/12 photoperiod with 1hr on between the dark cycle for vegetative growth.
Goes like this.
- 12 hrs on
- 5.5 hrs off
- 1hr on
- 5.5 hrs off
- repeat
Been running this light cycle for a month and the results are amazing. I would say this light cycle is superior to any other light cycle for vegetative growth.
For veg:
- 12-1 (Gas Lantern Routine) - Superior
- 15/9 - High
- 16/8 - High
- 18/6 - Middle
- 24/0 - Low
Pro:
- Saves electricity (11hrs of saving from 24/0, 5hrs of saving from 18/6)
- Promote healthy plants. Any deficiency it has the plant will be able to bounce back with new growth after adjustment is made.
- Promote plants growth, 2x more than 18/6, and 3-4x more from 24/0
- Cuttings will root much faster with thicker roots and more hairs
- Clones under bloom (12/12) will induce flowering much sooner
- Less on hours = less heat = stealth
Con:
- Must have good ventilation if the tent is closed or the tent has to be left open for the 1hr on between the dark cycle.
- Must have good odor control. Healthy plants produce more aroma even in veg.
- Plants in small container may get root bound due to rapid growth
Some tips using GLR (theory):
- Have the light on a timer so the on/off is consistent daily. Manual on/off may induce flowering.
- Use mix light or MH. Try not to use just HPS. The spectrum from HPS may induce flowering even with the 1 hour on between the dark cycle.
- For the 1 hour on use a cheap light source like Fluorescent light or CFL instead of using HID light. Have it on a separate timer only turn on 1hr between the dark cycle and have the HID light set at 12/12. Normally with any other light cycle the ballast is turned on once in 24hrs, with GLR it turned on twice. This may shorten the lifespan of the ballast and bulb. If you decided to run Fluo/CFL then make sure the tent is well lid any shaded area or area left in the dark may induce flowering. The 1 hour on between dark cycle help destroy floral hormone, lack of light will not be able to destroy the hormone and will send your plants in bloom.
I'm very impressed by the results from GLR. I give this light cycle a passing grade:
A+
You're safe to run this light cycle if you want. I'm using this exclusively for all clones/seedling/and plants in vegetative growth.
