🤠if you have no buds yet i hope you dont have just Hemp Seeds also when it does flower it will still be 50 to 70 days before harvest time good luck also i have put this up a few times before but dont know if you saw it so here it is 🧙‍♂️
🤠A few days ago, I asked a friend why did he remove leaves on his indoor medical cannabis plants. The tops of the plants were becoming crowded with big healthy leaves; and he was concerned about light penetrating to the lower branches. I was surprised by how many wrong and contradictory answers he had received from other fairly experienced growers. Hopefully I can clarify a few points and help dispel some of the misinformation floating about.
Try to think of leaves like solar panels. They are the plant’s only source of energy. The healthier the leaves, the more energy the plant has to grow and produce huge, resinous buds.
As the leaves on the plant begin to age, they eventually reach a point where photosynthesis peaks and begins to slow. At this point, the leaves are less efficient, and glucose productions declines. New leaves grow in to replace them as the primary solar panels, allowing more efficient photosynthesis to continue. The older, less efficient, leaves begin to work much like the root system, distributing their stored nutrients and plant sugars to wherever it is needed. When they have no more nutrients left to redistribute, these leaves will begin to yellow, and eventually fall from the plant.
This is particularly important to remember if you are experiencing root problems. Older leaves may be sacrificed to allow light to shine on fresh growth–but only if you have a healthy, robust root system. If your roots are not well established or are damaged, you may do more harm than good by removing the older leaves.
I should point out that most of the older leaves will be lower on the plant and therefor unlikely to shade much of the fresh growth. Any fresh growth lower on the plant is probably on shoots and in the shade of fresh foliage that is closer to the light. The principal of light and the inverse square law tell us that artificial light intensity quickly diminishes the further you get from the light source. So, you certainly do not want to sacrifice fresh leaves closer to the light for fresh leaves further away.
You can tell that leaves are beginning to give up their nutrients when they start to lose their dark green color. If these fading older leaves are blocking the light from new growth, feel free to remove them. By the time the leaves become pale green, or begin to yellow, they should be removed–even if they are not blocking younger foliage. Be sure not to remove leaves that have not yet reached their full size, unless they have been damaged by pests. Healthy leaves exposed to the light are facilitating photosynthesis. So your plants require them.
Outside, the Sun’s position in the sky changes through the day, providing light from a wide range of angles. Plants will follow the Sun and lower their leaves in the morning and evening to expose as much surface area as possible to the light. In grow rooms with stationary grow lights, the plants will only receive light from one static angle. This means that lower leaves are often shaded completely once new leaves grow in.
With stationary lighting, the only wavelengths that can penetrate dense leaves is from the far red end of the spectrum. This far red light does not assist photosynthesis, but triggers internal plant hormones called gibberellins. These gibberellins then cause the plants to stretch and create longer inter-nodal spacing. The lower, shaded shoots usually do not amount to much, but may draw a tremendous amount of the plant’s energy stretching towards the light. For indoor gardens, use selective pruning to maximize yield and redirect plant energy to more productive zones.
Removing leaves is not the only method of decreasing shading and increasing light penetration. Using light movers, you can supply light at a variety of angles. This can reduce stretch, and light otherwise shaded leaves. Oscillating fans can be aimed to flutter leaves, allowing light to penetrate deeper into the canopy. Reflective material on the walls will also help to redirect wasted light at angles advantageous to lower leaves. For smaller grow rooms, plants can be set at different levels like stadium seating. In theory, this works great; but it is difficult to implement in larger grow rooms, and virtually impossible with many hydroponic systems.
The best answer for improving light penetration is simply to grow shorter marijuana plants. With taller plants, the majority of the bottom branches end up in shade. Even if light did penetrate the upper leaves, the lumen s reaching the lower branches are so diminished that they yield poorly anyway.
What have you learned?
Do not remove leaves indiscriminately.
Do not remove young leaves unless heavily damaged by bugs or molds.
Do not sacrifice healthy leaves near the light for the sake of lower leaves.
Remove leaves that are beginning to yellow.
Do not remove mature leaves if you have a weak root system.
Use light movers, oscillating fans, and reflective material to improve light penetration
Grow your plants short to keep all the branches as close to the lights source as possible
Use selective pruning to remove sucker shoots that use up valuable plant energy This is what I learned growing Flowers over many years and most all plants and Canopy's even the Great AMAZON FOREST grows with a heavy canopy there is still plenty of growth on the ground because there is no one picking their leaves o well enough of this book. Later🧙‍♂️
Good stuff right there. It's interesting how you can get so many differing opinions about a topic, especially defoliation. There are as many methods as there are growers. Lots of reasons for and against and lots of right answers. Just try to absorb all the information, experiment, and do what works best for you.

I have tons of little buds that are filling in more and more everyday now. Was getting worried early flowering seemed to last forever before actual buds started to form

Here she is! Standing 6’6” measured her twice this week and she seems to have stopped her vertical climb.

I’m thinking of getting a medical license so I can grow more then four. Growing for more wife and daughter. Both have health issues I want to ease with proper strain selection.

I have one for 12g/day and the wife for 6 but never applied for a grow permit from Hellth Canaduh tho I've had mine going on 6 years, wife 2. Like a lot of doctors here in Alberta ours buggered off to BC a week after renewing us and I doubt I'll find another doc willing to sign by next June. They need to change the rules for people with chronic conditions so you don't need to do all this renewal crap every year. I'm supplying half a dozen friends with free meds plus the wife and I take RSO. She doesn't toke and I only a bit now. RSO ruins toking for you buzz wise but I still feel the medical effects from a toke.

Not much different here in Ontario. They are pretty easy here through your doc. I’ll mainly be growing for wife and daughter. I’m enjoying growing even if it is only my first go at it I definitely know it’s for from the last. My kids are with the in-laws in Alberta right know for a week.

A co worker just send me these two pics asking if they are ready for harvest. I think they are good to cut now seeing that he’s going for high THC

We got no docs up here and the ones we do get are from South Africa or middle east mostly and too new to want to get into the pot thing. The doc that was signing for me and teh wife refused me 10 years ago when he first came to Canada but after I got a doc in BC to sign me up he relented and began doing it for the following few years but now he's gone. I'm hoping with my previous approvals that will help getting a new doc to do it but I'm not holding my breath on that.

I've been growing here for 20 years illegally and not going to stop now but as I'm getting into growing outside it raises the chances that someone may eventually report me. My back yard is hidden from the highway by woods and we don't have strangers wandering around other than the tractor guy we hire once in a while to mow the grass in the back and do the dirt moving and roto-tilling spring and fall. He saw my plants last year and was more curious than anything. Says his nephew has been growing for years long before it was legal.

Not likely to see more than a small fine if I get caught tho could lose all my grow gear and that would hurt. I have a few grand invested in this hobby and real medical need for us and others so don't want to lose it. With the possibility that the Cons could get in thanks to dipshit's election call rules could change over the next few years too.

Harvest now or wait. Not mine a coworker wanted a professional opinion.
🤠if your going for high THC like Jason said let it go for at least another week let the trycones grow it looks pretty young and thin trycones are really where you get your THC from dont cut them until your trycones are cloudy and a bit golden thats where the top THC will be if you cut to young you will be lucky to get a 14% THC plant also your hairs look awful white they should turn a reddish brown but this is from an old growing man not a professional 🧙‍♂️

Growing techniques, opinions, tips, and advice are all subjective based on the individual grower. You can eliminate many growing factors by having a controlled indoor environment and optimum conditions. I totally agree with Jason about the mass of information that is avaialable out there and just try out and lock down what personally works best for your growing situation...

Trichome coloration during late flowering phase from cloudy is usually a sign of THC degradation when they start turning amber or golden. Peak THC is usually when all Trichomes are all cloudy, this is my usual time for harvest for a proper full plant dry and prepped for container curing. If you let your plants Trichomes turn to a more golden or amber color, you are allowing the terpene profile to develop into stronger more intense aroma at the cost of THC degradation...

Hi Uncle Canuck,

I’m no professional, just a fellow private grower and breeder like many of the other members on this forum. Your friend‘s female plants are way too early to harvest. I agree with AlphaToy and I notice all of the white colored pistils that are showing. These ladies are still bulking up and looks like they are approaching from mid flower to late flowering phase. Like Jason said, I would wait at
least a week, or two, or possibly 3 weeks before harvest until you can see that all of your trichomes are all cloudy. Pistil or stamen color change can be used as an early sign of your flowers maturing but you should definitely go by the Trichome development and harvest at the appropriate time to maximize your THC and cannabinoid content for maximum potency!

Let them girls develop.

Looking good brother! You're still in early flowering phase, I would add a little nitrogen and some sort of Phosphorus and Potassium booster to your next feed to supercharge your flowering phase and start bulking up early especially outdoors...

I swear everyday I notice growth. They are getting heavy and plump very fast. Even the wife took notice that they are bigger then yesterday so I felt better. Thought I was tripping out. Any ideas or thoughts on the leaves changing colours. Quite a few are doing it and they are still very much healthy.
