See here's wt I am talking about. If seedlings require 25watts minimum to branch and u put 7 under a 77 watt fixture then that is 10 Watts per plant. They will never get wider, u will overwater
No, at the seedling stage it's a function of pot size as seedlings have virtually no canopy.

I asked you about seedlings and canopy constraints under light. Could you please focus on that.

Nota Bene: Please add white space to your walls of text, thank you.
I don't know about white walls and all that. If you want to maximize growth you need to have your grow area (volumn per cubic ft length & width & height) filled with canopee 18-24 inches from the light in seedling stage before u go to veg. That means, while you are in a solo cup, your plants have to be 3x the width of the cup before you go into a 1 gallon bucket for veg. You achieve this by giving each plant 25watts minimum at a ppfd of 100 umol/s for 7 days, 200 ppfd for 7 days and 300 ppfd until your seedlings are 3x wider than the solo cup. This is filling up the space with canopee. I shouldn't be able to look through your canopee and see the backs of the wall or look down from the lights and see the floor or soil anywhere in the grow space if so, then you have not filled out your canopee. Filling out your canopee requires you to grow your plants wide and not vertical. Once your plants have reached they 4th node on the apical chute you top the apical node (never fem) and lolipp the lower first node leave only 2 nodes. This will stop the apical growth vertical and start the branching width. The 2 nodes left will grow 4 branches then once they have branched maturity you fem (not top) then those 4 nodes will have 8 nodes then you fem again (not top) then you will have 16 tops before your seedlings is even 30 days old. Now your plant has 16 tops, it will be wider than the bucket, it will hsve filled out its MAX volumn of canopee for its space and will now be ready for Veg (each plant gets sane treatment). If you don't feel out the canopee during seedling stage under your T5s or LEDs u end up with plants that never filled out its canopee because it never got wider than the bucket so u put in 1 gallon bucket with no branches it gets overwatered and grows vertical and never branches the roots die from overwatered u get mag deficiencies etc. You must fill out all the canopee during seedling stage before you ever move to veg or u will never fill it out later because the plant matures in veg, it will never branch and u get those tall apical chutes that run into the light and popcorn buds at the bottom before it never got light as lights can only penetrate 18-24 inches past the apical top so nothing less will 25" will ever develop branch its to late u will have plants tall and skinny with no branches and 70% missed yield overwatered and since u missed 70% of canopee u had more light hitting the floor and soil then light hitting the plant meaning to much light

Bullshit seedlings have no canapee that's because you don't know what your doing and I can tell by your statement u are a plant killer because all my growers have full canopee (16 tops before the plants 30th day before they move to veg. During veg they turn 16 tops into like 100 so don't tell me seedlings don't branch or develop canopee just say u don't know how. See, your correct statement should have been teach me how instead of saying seedlings don't get canopee, Plants are all canopee. 99% of growers don't know what they doing so when they loose they think they winning. You see mostly failed grows so u have become a custom to failed grows. I don't want to insult u I apologize not my intentions. Here let's do this, if u want to achieve a full canapee with 16 tops while your in seedling stage here's my email and from a Engineering perspective as I am a Biosystems Engineer this is all I do. Emaile me I'll tell you why, how, when and where then u go start winning so u can shit on your friends. The moment someone comes to me about nutrients and lights then I already know they are nutrient and light salesman and failed growers. Good growers know yield is based on maximizing canopee from usable light Photons and quality is based on grower talent. Its never about nutrients, pH, vpd or any of that bullcrap yall talk about ever, if u talking about vpd your a plant killer because only people who give to many nutrients burn they plant talk about oh my vpd isn't right. Nooo, your a shitty grower who was taught by another shitty grower.

1. Let's see you led with lights are consumables and the room becomes dimmer as you have more people in it. Light is not a consumable.

2. You use the Appeal to Authority fallacy.

3. You go ad hominem

4. Finally you are incapable of spelling canopy.

Please stick around and learn to grow cannabis.

Pics Please!
I don't need to produce pictures, only growers who fail they grows say pictures please. Because good growers always respond with grower talent responses such as dude, my girl hates trimming and my plants always get wider then the area, I need a bigger tent. If all you have to say is pictures please then I know you are the type who's plant never gets wider than the bucket, overwater, to much light, believe nutrients gets you more yields, say pH lockout, apical runs into the light and gets 80% of there yield and say next time I'll do vpd. See the reality is most growers is so far from the truth u have convinced yourself your a good grower yet u still believe more plants means more yields. Ur plants don't branch, u ask how far should I hang my lights like !!.

Once again, everything you said had nothing to do with growing. Out of everything all you had to say was LED's and dimmers. That's what I'm trying to say. You growers only say 2 words LEDs and Nutrients. You are so caught up in lights that u don't even understand how to pull a 1500 ppfd canopee yet talk about LED like they will save your garden. Truth still remains, plants never....stop stop wait, since u want to talk about pictures post a picture here and I'll tell you if your winning. Don't post someone else stuff either. In the background write rollitup and in 5 minutes I will pick your garden apart. If your garden is right I will say dude great fucking job. I'll tell you why and if it's shitty I will pick it apart. If your plants aren't wider than the bucket right off top I am going to pick it tf apart.

You showed up today. @HydoDan asked you for pics. You go first. If you want to see pics of my plants there are tons of them on this site. Avail yourself of the search feature.

Frankly I think you're simply an angry kid out to troll a site. I do not believe your mom allows you to smoke much less grow cannabis and I think meth is bad for your health.

Kid? Dude, I'm a 37 year old black male from Minnesota. I have a PhD in Agricultural & Biosystems Engineer since 2011. I am just posting a thread and accidentally posted under someone thread as I am new to this site. Just trying to post my thoughts it's not a issue. I don't need to view your pictures, I'll never teach someone who is defensive. I rather focus on those who want a full canopy by day 30 seedling, not overwatered, save on energy bill by not lighting soil and floor.

Someone argued me down that plant count equates to more yield. He was so far away from reality yet he argued me down just like u until he invited me over to his great garden and what was the first thing I see,
He was in a 5x5 tent with to many minaturized plants in a 3 gallon pot 4x wider than the plant, no branches, all soil, purple stems from mag deficiencies and last grow missed 90% of his yield and he didn't know why. He been listening to all these forum's saying hang your led 12" above the canopy. I put all his plants in the corner and he had 75% unfilled. If 75% is empty no canopy then by definition he had to much light, to big a pot, to many plants and he overwatered. He finally called me after failing 4x in a row he never made it to flower. I'm only here to help those that are so far from reality. I identified all those errors in his garden and his solution to fixing the failures were to manage vpd and pH and a bigger light. One of his problems were to much light yet he wants a brighter light with 1500 PAR and co2 so he can kill his plants faster, he didn't know light equates to yield, he still thought more plants meant more yield. He wouldn't believe 1000 Watts is 2 lbs and 20% more with co2 and a ppfd above 900. He was so far away from reality like 99% of growers are. I told him start over and he said no. Called me 4 days later and said OK your right they are dead. He thought because they not breathing they aren't dead. He killed his roots with to much water because they were in to big a pot, plants never got wider than the bucket, he had no branches he didn't know where buds grew he asked where. He pulled off all his fan leaves and wondered why his plant stop growing. I just want to help growers make better cannabis then the dispensaries, achieve over 2lbs per 1000 watts with less plants, less soil, less training, half the veg time etc.
