So I finished work yesterday and I was in a rush to get back as I needed to water my girls the lights go off at 5pm and got back at 430. So anyway I watered them before lights out and I'm sure I've seen somewhere that you shouldn't do that. So I go in there this morning and the growing has gone fucking nuts over night. Whether it was that or whether it's because everything is now on point and they have just decided to go on a growing spree. What do you think? This 1st picture was taken I think Friday or Saturday still can see some floor space in the centre . Today I'm thinking I'm going to have very little room in there soon haha. I'll space them out again later today. Happy growing people Sent from my iPhone using Grasscity Forum
Out of curiosity, do you happen to know why that is? Also, congratulations on the new growth @ Deano. They're looking fantastic!
when the lghts go out they assume they're dying, an focus all the energy they can on surviving, an suck up all the nutes
Think that's when I'll start watering them. I won't give nutes then as its not good going to bed on a full stomach Thanks max I couldn't believe it like when I went in this morning. Getting the hang of this growing thing ha. Well will see when it comes to seeing what yield I get eh. Thanks for the info lads Sent from my iPhone using Grasscity Forum
Ah ok. Think I'll start doing that then. Can't believe the growth this morning. They've gone crazy. Been in tower 1 week now. Sent from my iPhone using Grasscity Forum
Watering mine last thing say 20 minutes before lights out hadn't done then no harm. I don't really know much about it but there's been mad growth over night Sent from my iPhone using Grasscity Forum
Note: diels alder was instrumental in helping turn this very technical subject into something much easier to understand. This is by no means a complete, technical explanation of Botany, rather it’s an understanding of the basic principles. Many times I’ve seen in posts that “roots grow during the dark.”. If this were true, the 24/0 photoperiod would result in a plant with a tiny root structure, if one at all! We know this is not the case - so how does it actually work? To simplify things, lets use an analogy. Try to think of a plant as a building… one constantly under construction. The plant needs raw materials, (fertilizers and water), and energy (light) in order to “build itself”. The raw materials are the “bricks and mortar” of the building. The energy is the workers, vehicles and power tools used to assemble the building. The Plant is capable of storing some raw materials and some energy for use later, but the amount is limited...think of a warehouse and a battery. * During the day, (Lights ON) the plant is collecting and storing light energy, and is using and storing raw materials. The plant is stockpiling raw material, and is charging it’s batteries… it is ALSO using raw materials and using the energy it is collecting. It’s building itself, literally putting itself together. During the day however, the plant is not as efficient at building itself, as it is at night (lights OFF.) It can build itself, but not as quickly. * While the lights are OFF, the plant is using energy and raw materials to build itself…. the plant is more efficiently using the raw materials that it stored during the day. The plant is better at transporting and assembling the raw materials. The bad news: since there is no light energy, the plant must rely on energy it stored while the lights were ON (its stored energy). (Essentially, the plant is running on batteries, and using raw material from the warehouse.) There is no light energy to collect. Since the plant needs energy to absorb more raw materials, it is easier for the plant to use raw materials that it stored during the day than it is to absorb raw materials through its roots. * Although the plant IS capable of “doing it all” with the lights on, (Collect, store and use energy & raw materials) it does a better job of actually doing the work (using the energy and raw material) while the lights are out. During the dark however, it relies solely on its limited supply of stored energy and stored raw material. One last thing to remember is the fact that a plant will always strive to maintain a balance between the size of its roots and the size of its canopy (Leaf mass.) The roots must be big enough to supply as much raw materials as the canopy can use, and the canopy must be big enough to provide the energy required to store those raw materials…. * Trim the roots on a healthy plant, and canopy growth will slow to a crawl until the roots have grown big enough to again support the canopy. * Trim the TOP of a healthy plant, and root growth will slow similarly, until the canopy has grown big enough to again support the roots. * If the plant is already in balance, the canopy and the roots will grow at the same rate. If you actually measured them several times daily over several days, you’d notice that they actually DO get bigger at night, but roots and canopy at the same rate, unless either has been trimmed, and as long as the “batteries” hold out. / try it
A couple weeks ago my timers broke whilst plants was in veg and ended up being in 24hrs lighting. Now the plants went down hill rapidly as they must of been in constant light for a few days. Once I sorted it 2 days they was looking better than ever. So personally I don't know about that 24hr lights on thing maybe from the start but deffo not good weeks into veg. Ha. Anyway it's all good learning and being my 1st grow. Kind of thrown myself in the deep end with 11 plants haha. It's all good fun eh Sent from my iPhone using Grasscity Forum
Please tell me how any of this relates to a plant "assumes its dying" when the lights go out? Simply pasting what you said above - "does a better job of actually doing the work (using the energy and raw material) while the lights are out." So the plant is doing a better job at night - because it thinks its dying?? Oh - one other thing - are you "SmokeyMacPot" over at 420magazine forum? J
Plants do grow more during lights out. Same as muscle building your grow during your sleep as your resting. I dunno about the plant thinks dying side of things but I do know they do most there growing during lights out Sent from my iPhone using Grasscity Forum
It doesn't think it's dying. Your plants were able to absorb the water better during the dark period. This is because while the lights are on, stomata are open, CO2 is being exchanged and photosynthesis is taking place. When the lights are off, all of those processes stop. (Stomata close). This allows the plant to focus on absorbing what they can, and where they can at that time. Also, your plants aren't retaining as much water while the lights are on. 1 reason being the increase in transpiration that takes place due to the increase in heat and photosynthesis taking place. Second reason being that the water can be easily evaporated from the soil if you water when they are on, leaving less for the plant even though you are watering the same amount.

Cannabis is a C3 plant which means that it does not require a dark period and in fact continues to grow as long as it has light - but take a few minutes to read here - Need the dark | Cannabis Culture J
