Why not 24hrs. light during VEG.

Photo #10 should do it.

https://www.rollitup.org/general-marijuana-growing/9114-spin-out-chemical-root-pruning.html

As I've told every new crop of newbies that drums up this timeless debate for the last 10 years, plants do better with a rest. This 24/0 thingie is symbolic of the (feel-good) need for growers to push their plants (and usually end up screwing up the results compared to others that follow normal plant culture.) More light, more nutes, more water, etc. DOES NOT guarantee better results, it actually works against the grower. You need to find out your garden's light saturation point and go from there. If you don't understand the concept of light saturation, then you're pissin' up a rope no matter what photoperiod you use.

Male at 4 weeks veg using 20/4:

Your root ridden clump is hardly proof that 20/4 or 18/6 works better than 24/0. We could pull out one plant each from 100 random grower's at 4 weeks and if they all did 20/4 each plant from each grower would have a different mass amount of roots. This pic just shows us you know how to grow in veg, it DOES NOT show us that 20/4 is better than 24/0. The ONLY benefit of using a light cycle other than 24/0 is to save on electricity.

Read the thread. Having said that, that is a pretty damn robust root system for less than 4 wks. veg. A lot happens regarding plant processes during a rest period.

Gonna give you some friendly advice. Don't come in here as the typical low post count, smart ass, swingin' dick, know-it-all noob. Try some humility as it's obvious you don't have basic horticulture down pat --> https://www.rollitup.org/marijuana-plant-problems/477382-16-day-seedlings-not-looking.html#post6474830 For 16 day old seedlings, those plants look like crap and are never gonna amount to beans. Once stunted like that, it's hard to recover if ever. Curious, are they even alive anymore?

I tried every light method out there. I even experimented with clones off the same plant. I used 3 methods of lighting and a 4 week veg cycle. 24/0, 20/4 and 18/6.

The plants on 24/0 were slightly shorter with slightly closer nodes. The down side is that they looked much more "tired" than the others and took longer to flower.

The other two lighting cycles were very close to each other in size and shape. They were slightly taller than the 24/0 but they looked way more robust than the others.

I then said fuck this bullshit and went with a 16/8 light cycle for economic reasons. My plants love it. They may be an inch or 2 taller than the other cycles but they are healthy and beautiful. Plus I save 33% on electric compared to 24/0 light cycle users.

For those that want to save some money go for it. The difference is negligible in the output of each plant. Some clones do grow better than others but the numbers didn't lie in the end.

The 24/0 plants averaged 2.62 ounces per plant but took a week longer. The 20/4 plants averaged 2.6 and the 18/6 averaged 2.59.

The same clones on my 16/8 schedule average 2.58 ounces per plant. Less electric use is for me any day :blsmoke:

Hope this helps:

Edit: With a basic understanding of the compensation point, saturation point, and photosynthesis you can probably see why a plant would need some "down time." Sure, 24 hrs of straight veg works... and I hear that argument a lot: "It works, fuck you!" What that crowd seems to be missing is that we're growing fucking weeds. You know, that thing that grows in nature if you just leave it the fuck alone. It's amazing how people don't seem to understand that most things will "work." That doesn't mean that they're working well.

Great article 420johnny! I remember stumbling upon that article when I first started this flower growing business two years ago and it was extremely helpful for me!

Well it's a bloody weed. I've had it before where i've thrown seeds in the garden to find a plant a few weeks later (during hot and dry summer) that is looking nice and green and healthy. And the best part is it is just sitting in plain old nutrient derived sand.

Now a mate who has studied horticulture would recommend 18/6 light or even 20/4 light. But i mean do what works for you, if you ask me, throwing some seeds in sand has produced bud before just the yield is not as good as using good organic soil, the point is it'll work.

I'm sick of seeing over zealous growers who over fertilize their plants if anything i under fertilize when on a new strain (of any plant im talking about here) then i quickly bump it up if i see deficiencies with foliar sprays , etc. I get better tasting tomatoes for it too by using the right amount of fertilizers.

My soil mix for good quality plant growth of almost any plant:

four bags of high quality potting mix with no fertilizers added
two bags of mushroom compost
two bags of cow shit
two bags of chicken shit
few handfuls of blood n bone
some dynamic lifter

I'm not saying to use it at all, use what works for you, this is what works for me.

I vary the mix depending on what is being grown , sometimes i remove the cow crap as that sometimes is too much for certain plants.

EDIT; if you guys want even better success then SETUP A WORM FARM, buy those packs of 1000 starter worms then feed it all the food scraps then collect the worm castings and juice. Mix this into your soil :)

Im using just a basic potting soil, seams to be working great... also has a 6 month plant food realease so that should get me through this harvest all right?
nothing has a 6 month release or atleast nothing ive seen in a POT...lol

TLDR the thread. I suggest 18/6 over 24/0 for a few couple reasons

Less electricity and more simulation of nature (e.g. dark period). 24/0 just isn't necessary... It's not bad, I just don't prefer it.

1 - 24/0 does work for veg and some plants grow faster depending on the light your using over 18/6
2 - People use 18/6 to keep the cost of their veg room down but some people don't care that it cost them a little more.
3 - If you don't have the ability to wait for the light to come on and or want to be able to pop in and out of your veg room 24/0 might be best.

Since electricity is getting more expensive, consider getting a HO T5 (8 bulb= 432 watts). I have a Quantum Bad Boy. It has 2 o/o switches AND I can run 2 bulbs at a time: 2 is all you need during early veg/clone. As the plants develop I can increase number of bulbs 2 at a time.

I use a 18-4-9 with micros, 12 month release. Same type product as Osmocote.
wow so you have soil in a pot that lasts 12 MONTHS with adding NOTHING just plain ph water for 12 months huh?? lol what size pot is this and where can i find soil that will not need anything and sustain growth for 12 MONTHS in a 5 gallon pot??? id love to know because you must have some magic mix that we all need to know about....

Yep (LOL)

Like I said, it's an encapsulated food, like Osmocote. Google 'polyon'.
I know what you are talking about, this slow release food is OK but it does wear out quite fast when i.e a fast growing plant such as a tomato plant for all intensive purposes takes all the nutrients up.

I've grown in soil that is just compost before and the results have been absolutely amazing.

back on topic

go talk about soil in another thread.

16/8 for moms, clones and veg cycles.

UB should know better :finger::twisted:
