Welcome to the Solo Cup challenge 2020!

Our mission is to create a tight nit community full of people that have that one beautiful thing in common. Love for cannabis plants!

We created a challenge or "contest" that will be a serious examination of a growers' ability to apply all their skills in just a 16oz solo cup!

Anyone is welcome to join!

Good luck!

Rules:

  • You Must start from seed.
  • Absolutely no clones are permitted.
  • Photoperiod and autoflowers are welcome of ANY strain, and ANY breeder.
  • There is a 5 week vegetation period cap for ALL photoperiod varieties.
  • Must be grown in a 16-ounce solo cup.
  • No matter the medium roots must stay within the cup at all times.
  • 1 picture per update MUST contain 1 picture of the full plant and a full cup.
  • Plant and roots can leave the cup to swap water and nutrients in hydroponic setups 
  •  Any non-solo cup entries must provide proof of volume. IE... size marked on the container.

Happy Growing and good luck again!

@DonaldTrump,If contest shows interest, Recieves quality entries... and people can remain civil! I'll certainly get the wheels in motion and see what we can drum up. Making this community great has always been an agenda of mine! Once the kinks are worked out in this one... busy writing shit up to word everything for the last time. Than ill Reach out to my fam n see if I can whip together something SWEET!

@416fireman, As a leader it's all about honesty and integrity! That's why I'm here to make GROWDIARIES Great Again! With a contest like this you are helping out with this Great Cause. It would be nice if you could run it 2 times a year maybe every 6 months. :+1::+1: From The White House.

As I embark on a new adventure. Change course and head in a new direction with my cultivation. I've decided on a re branding... I dont want to juggle multiple aliases and accounts... and streamline right into an already apparent issue on this platform. With a new mindset and mission I decided to go with a new account. This is the beginning of SpliffSeedsGarden so I want the account to reflect that. That being said I've kept up with this contest and will continue to do so. Good Luck to ALL Contestants!
Happy Growing and stay lit fam.

Sincerely

I appreciate ALL the growers that are following the rules. I Respect and Appreciate each and every entry. It's of my utmost concern everyone gets a equal and fair look and shot at winning. To me a name and rank means nothing without integrity. I'm not participating and am here solely as moderation. Have faith that the ones moderating the contest are competent. Respect me by respecting everyone that wants to take part. Without giving me a opportunity to do things the right way. You directly show disrespect and lack of leadership. Not just to the person and myself... but to the whole community. Not the characteristics of a real winner. Deal with me about any concerns.... bottom line be respectful fam! I'm devoting time and effort each and everyday towards this contest. All for the love of this community! Again with much love and respect GD community.
Sincerely 416fireman

@GreenMachine, You are entitled to your opinion just like I am. I could give to fucks what you think. I mean that in the most respectful way cough cough.:+1::+1: From The White House.

@DonaldTrump, if you had faith in him you would sit there, enjoy the companionship of your plant, and share how your style of growing works for you. If you need to dissect "fellow" growers entries looking for technicalities to disqualify them then that shows your lack of confidence in your capabilities. Not theirs. I am far from an expert grower but I am pretty confident that I could limit my roots to 12oz and crush anything you could do in 24 or even 36 oz of roots in weight and quality. Basically....my opinion is you should shut the fuck up and harvest a plant before you try to govern anything around here. I mean that in the most respectful way. Troll on...

@GreenMachine,I respect the guidelines of this challenge.I stated days ago the faith I had in 416fireman. I also only have one account. Even if I had 100 accounts joined in this contest it's not against the rules.It states you can only win once.That's why I'm in the White House and you are in the Outhouse. I already told a fellow contestant when I won I would gift the seeds to them. I was in it for a challenge not to drill a hole in my cup and have the roots go into another substrate.:+1::+1: From The White House.

Personally attacking participants is un called for and hard for me to tolerate... If you have any issue or concern regarding another participants entry. Feel free to DM me and the matter will be investigated and dealt with appropriately.
If I cannot personally solve your issue or answer your questions. The GD staff can and will be involved to get to a resolution. The whole point of this contest is to bring our community together! Poisonous actions will not go un noticed. Grow diaries has givin us a opportunity to choose our own contest! How can they fathom doing it again if yall act like a bunch of children! With much love and respect! Happy growing and stay lit fam.

@Huggomadd, legit it’s hard to find solo cups where I live 473ml should be fine, after all we might not all be lucky enough to live Canada :rocket::rocket::rocket:

DanBilzerian

@Huggomadd, You can use any 16 oz cup or container. Need proof it's 16 oz or 473 ml. No roots can leave the cup.

@ShotGunBob,
I know right... Solo cups only means that you MUST use a Solo cup. Any plain 16oz. cup won't suffice my peeps'
