Is this normal?

[louise]

Not sure what you mean Vortex by 'calmer on the plants'... 24 hr lighting is more stressful than breaking the light for a dark period... and it's not like you will disturb a vegging plant if you turn lights on during the dark period... that is only an issue for flowering plants.

 

The biggest difference I noticed between 18/6 and 24/7 was on the elec bill... 18/6 cost 25% less to run.

You can sex the plant ad1988, once it is a plant as opposed to a seedling. This is generally seen as shown by the development of 'alternating nodes', where the internodes rather than being opposite, due to the plant stretching are at an angle from each other.

 

Am confused by what you mean't as per above comment can you elaborate ? Thanks

[Vortex]

Sorry for confusion. Calmer because plants are growing at a constant temperature, no stops and starts.

 

Miss out on temp drops, night time damping off of sprouts, and nocturnal pests. [ though a daylight caterpillar on 24 has the edge]

 

Easier on equipment, you use more power turning on and off, each time you turn on is when strain on electrical components occurs.

 

Calmer on me because no timer and can deal with vegging plants any time of day.

 

Anecdotal evidence is 33% more growth on 24. GOOGLE 'cannabis is a C3 plant' for some testimonies, Ed Rosenthal being the original mentor.

 

Best wishes, Vortex

Sorry again, Mark601.

 

The seedling has its leaves on opposite sides of the stem, at an even height. The point where the hit the main stem is the internode.

 

As it becomes a plant, the internodes are no longer at same height, but opposite each other at an angle.

 

Plant goes from a seedling just establishing roots and first leaves, to a plant thinking about putting out lateral branches , so development of alternating nodes is accompanied by the development of growth out the internodes.Best wishes Vortex

No worries Vortex, thanks for taking the time to expand. I agree with you on some points, 24/7 does have some advantages over including a dark period... especially when it comes to germinating seed and rooting new cuttings.

 

But easier on equipment.... afraid not. You shorten bulb life by a lot more by leaving it burning than what you would lose switching it off for 8hrs once a day. True of fluoro technology 25 years ago, but not relevant to current tech.

 

You might have missed this bit... "and it's not like you will disturb a vegging plant if you turn lights on during the dark period... that is only an issue for flowering plants"?

 

I'm not suggesting you walk in and flick on the HID, but it doesn't matter to a vegging plant if you flick the ceiling lights on during the dark period... you can work at anytime of the day or night regardless.

 

Finally, I do wonder whether Ed actually writes that column... that bit about 33% is patently false and dependent of on assuming that C3 plants only grow whilst actively taking up CO2. It doesn't matter that a C3 plant doesn't take up CO2 during the dark phase... it doesn't have too, that part of the job is already done. Sugars are manufactured and stored during active photosynthesis... the light period. After lights out, 'light independent' reactions release the stored energy to manufacture new growth. There is no need for CO2 uptake to use stored sugars... CO2 is used to make the sugars.

 

There is a lot of botany online that is more reliable than CC, if you are interested in the growth of C3 plants, look up the Hill Reaction... it shows how the production of O2 can exist independently of CO2 fixation during the dark period.

 

All the best for the rest,

 

lou.

Cheers Vortex thanks for explaining

[Vortex]

Most of my lights are from 25 years ago lou lou, .

 

Thanks for the reference, i'll put it on my homework list.

 

Ed not real? I guess you could call him a franchised legend. The figures and some of the reasoning behind it is anecdotal.

 

For me it's more convenient, keeps everything constant and i am happy with the simple logic of 6 hours more growing time for sprouts and seedlings. The other reason i forgot to mention is security.

 

A veg area on 24 becomes part of the household or background electricty, rather than something distinct like lights on for 18 and off for 6. Disguising 12/12 is still an issue, i ran flower at night when you would expect usage, dropped in bits to below 12 anyway, but a local blitz on meter readings hunting grows has me packed and relocating.

 

Glad it's sorted mark601. How are the plants coming along ad1988? , Vortex

[ad1988]

hey everyone, sorry iv not replied, been busy moving house.

 

plants are great, however the light green one is still a bit weird.. it just isnt there. its perfectly healthy as you can tell from the close up pics of the leaves, but its growing strangely.. its like it cant hold its own weight, it grows kinda sideways and the main root is coming up out of the soil. it had to have bamboo supports on it for a week. i dunno why its doing this, loose soil maybe? other than that its perfectly healthy.

 

i have reduced light from 24 hours to 16 hours, i dont know if this is responsible for the growth spurt in which i have seen, or that i have changed a bulb to one which really warms the cupboard up.

 

below are pics from 2 wednesdays ago, followed by pics from the wednesday after -

what do you think? is all looking well? any tips or comments?

 

ps - the pots. are they gonna be too small later in the plants life?
