^ There has been way to many debates about what to run while veg. 18/6 20/4 ( what ill use ) and 24/0. These debates go on and on. Just do a search and see. Why do I run with a dark period? Because that's what's supposed to happen. More things are happening in the plant with a dark period than you think ( look it up ) its science so why cut it off even for only 4 hours ? What's the benefit to running 24/0 ? I mean I know the plants will do fine and do not need a dark period but still If you have any scientific research not just what you think or see please send it. I'm interested Real evidence please. I'm always open to new material. Thanks.
Plants do something's in the light, and other things in the dark. It's all about getting the right balance.
I've run 24/0, 18/6, and recently outta curiosity tried the old Skool Gas Lantern Routine: 12 on/ 5.5 off/ 1 on/ 5.5 off.
Conclusion
24hr lighting produced slowest rate of growth with the tightest internode spacing.
18/6 quicker rate of growth to 24hr but more stretch/spacing between nodes. Healthier looking plants in general As well as less electric used.
GLR fastest rate of growth, with the healthiest looking plants, and tight node spacing.
