Grow 2 Diary 1: DIY RDWC Grapefruit Haze

Grow Diary - First Installment
Hello fellow growers!

Welcome to the first installment of my grow diary. After finishing my first-ever grow and taking some time to reflect on what worked and what didn’t, I decided to jump back in for round two—this time with a bit more knowledge. I hope you enjoy following along on this journey, and I hope someone can learn from my mistakes, and maybe I'll learn some more. Please feel free to comment and discuss. I might regret this later, but since this is my first grow journal, ignorance is bliss!

Lessons Learned
Looking back at my last grow, I identified a few key lessons that I promised myself I’d address before starting this new one:

  1. Root Space: A 5-gallon bucket seemed like a good idea at first, but as the plant grew, it caused problems—especially when dealing with a high-yielding plant. Watering and lifting a plant that’s holding 600 grams of buds is no joke. So, I decided to upgrade to a recirculating system with a 10-gallon capacity.
  2. Grow Space: While Sea of Green (SOG) works for many, it doesn’t really fit my style. I’ve learned that less can be more. This time around, I’m focusing on just one seed in a much larger space.
  3. Nutrient Line: I’m sticking with one nutrient line and including some supplements. I’ve also decided to reduce PPM levels by at least 20% from the feed charts.
  4. Record Keeping: Keeping a detailed diary throughout the grow is a must. It’s going to help me track progress and learn from both successes and mistakes.
Set-up Part List
I had three main goals for my grow space:

  • Reservoir with Tubing/Pipes: It must have a reservoir that was attached via tubing or pipes, and I had to have them on hand (no more costs).
  • More Space to Grow Evenly: I wanted to make use of the two levels of scrogs (time to cut my LST teeth).
  • Odor Control: Almost 100% odor control, with kids and a wife and people coming over, it’s super important that there be as little smell as possible.
I didn't include pricing or links, but I can add those later if people want to know.

Pictures with Explanations
Here’s a look at my setup during different stages of the grow. You’ll see some slight changes as I get the pictures up and taken.

Let's start with testing and proof of concept:

  • front pic.JPEG: This is a proof of concept mid-way during the build. I wanted to get an idea of spacing before I started to clean up the wires.
  • grow tote.JPEG: This is the inside of the grow tote. I intend to extend the pipe to the front of the tote to keep those nutes mixing (I had not added the stones in this one).
  • resevoir tent.JPEG: Here is the reservoir tote during water testing. The bulkhead on this one was leaking, but after a quick sanding, we got a good seal.

Seed Information and Other
  • Autoflower Grapefruit Haze: Grapefruit Haze Seed Info
  • Conditions:
    • 22-24°C
    • 70-85% humidity
    • Distilled water
  • Seeding Dates:
    • Seeding date 1: August 17th (no movement), Jiffy puck.
    • Seeding date 2: August 24th (still early), Jiffy puck but with less water and slightly higher numbers.
    • Seeding date 3: August 31st (hopefully don't need), GH rapid rooter plug.
I'm really looking forward to building this and chatting with you all. Hopefully, my seeds take and I can begin updating.
 
Grow Diary - Part 2
Date:
August 28, 2024

Long time no see! Overnight, there was some movement, and Seed 2 is on the grow. Super exciting, as I had already panic-set up a secondary seeding site for Seed 3.

  1. Seed 2 Update:
    • Seed 2 is showing movement, and preparations are underway for transplant and veg.
      we have life.JPEG
  2. Tent Adjustments:
    • HVAC moved to the top of the shelving space.
      changes to the setup.JPEG
    • Light adjusted to within a few inches of the top of the tent, providing about 6 feet minus about 5 inches of working space.
      increased light high.JPEG
  3. Air Pump and Tubing:
    • New tubing for the air pump installed with added valves.
    • Reservoir and grow tent on separate lines.
      airpump lines and extra control.JPEG
  4. Seedling Space Setup:
    • Temporary seedling space created on top of the grow tote to minimize plant shock during transplant.
    • Once the cotyledons are fully grown, the main light will be used at 10-15%.

  5. Smart plug in tent set up:
    • Placed a Geeni 6 plug smart power bar in the tent for timing.
    • Two open slots are available for the heat mat and seedling lamp.
    • All timing and related functions will be managed here.

  6. Started stats diary within the VIVOSUN app, I don't have SGS in this tent so I'm going to have to tweak environment as we go.

  7. Water: After the seedling stage ill be almost 100% using tap water, its tends to be about 8-9 ph and 90-130 ppm.
This grow will run through the change of season for me and there will be some fun when the house moves from dehumidify and cooling to Humidify and heating. Last time this was a 2-3 C change down and 8-10% jump in humidity.

Finally here is my super skilled drawing of what i had in my head for this project

Today’s Lesson(s):

  • Patience! This is growing, and you can’t dictate—only guide. If you think it’s time, give yourself 12 more hours.
  • Double-check your stat sheets before you spend hours building something.
  • Get over publish button anxiety, just post it. i made a mistake and the world didn't end!
