DISCLAIMER: The photo and video content posted here was originally for a different audience! I CAN NOT stress that any more. This grow was only documented to show my close buddies (who do not grow their own cannabis) a few steps along the pathway. I, of course, wanted to "flex"; but also wanted to answer a lot of their questions since I am the first grower they know personally. The language used is extremely casual and relaxed for a laymen (i.e. - instead of using common terms like "scrubbing the air" or "passive air intake", you'll hear "take the smell away" or "that lets air in", etc...). In addition, the notes posted for Season 1 are word-for-word from my personal journal. Meaning, 1st person POV, at some times sporadic/random, personal, and best of all - embarrassing. HOWEVER, these are 100% genuine thoughts, processes, experiments and failures that I think new growers can benefit from by seeing my experience. Not to mention, you can see what I did and what it resulted. Again - THIS CONTENT WAS NOT INTENTIONALLY CREATED FOR THIS FORUM, rather a couple curious buddies from way back in grade school. Enjoy...
I'm hoping the commonly called upon knowledge gurus like @Aqua Man and @Moe.Red will be able to pick my mistakes so I can avoid them moving forward and progress toward getting the full potential out of these genetics. Also, admins if there is any inappropriate language or images feel free to delete this and slap my hand. I'll make sure to follow the rules.
I'm very long-winded (as you can tell from my introduction and the disclaimer. So, if you're in a rush or don't about reading, just check out pics and vids until something catches your eye... then read! :D
Day 0 - Germination 0 [Sep. 5th, 2022]
Temp: 76F
Hum: 42%
Identification – bamboo = Glueberry OG, plastic = Deleted Scene
Today was just setting up the tent and getting environment dialed in. In natural ambient conditions of the home, and inside the room, temp was 76F and humidity was low at 42%.
Set up basic no RO humidifier. Brought humidity up to 80%, then turned off humidifier to see how fast it drops. Lights, vent, and fan all off. Drops pretty fast. Will need to run humidifier constantly and will have to find out a way with the in-line ventilation fan and the 6” clip fan to keep it stable at 75F and 75%.
Goal: 75F and 75% humidity.
Played around with humidifier, 6” clip fan, and inline vent fan. Found settings to stabilize 75F & 75%.
Settings:
Started germination today. Dropped 1 seed of each strain into gro-blocks and saturated gro-block with regular sink water. Started without dome on the tray, but within a few hours tops of gro-blocks felt a little dry since clip fan is directly blowing directly on them. Placed dome on top of tray after re-saturating gro-blocks again. Going to leave dome on tray.
Day 1 - Germination 1 [Sep. 6th 2022]

Light Height: 32” above gro-blocks
Identification – bamboo = Glueberry OG, plastic = Deleted Scene
Started the light cycle today, even though seeds don’t need light to germinate. Just want to lead them in the right direction (up) once they pop and asap. I may be putting too much love on them.
Yesterday, when I noticed the gro-blocks drying out on the tops from the clip fan directly hitting them, I poured water over them which of course over saturated and started to fill the bottom of the tray. I immediately soaked up the water on the tray floor and placed the dome back on. I’m wondering if I have already made the rookie mistake of overwatering and creating an anerobic environment. Ultimately, delaying germination until the gro-blocks can dry out a little. We’ll just have to wait and see.
No visual activity yet. Still just seeds sitting in gro-blocks. Not watering or changing any parameters. I did however open the tent all the way to see how far I’m hanging my light. Don’t have a PAR meter yet (too expensive right now) so I’m going to follow my YouTube growers advice on height and power. Those adjustments are still to come.
Seems as though the humidifier I took from the girls room works well, and with a full tank can go for 12+ hours. Really want to see how long the full tank will last – just to know.
Dropped light down to 32” above gro blocks and kept on lowest power setting - based on what I read online.
Day 2 - Germination 2 [Sep. 7th 2022]

Light Height: 32” above gro-blocks
Identification – bamboo = Glueberry OG, plastic = Deleted Scene
Dropped between 10-15ml (about a tbsp) tap water on each gro-block. Bottom of tray showed slight amount of receding vol. of water. So, I assume the gro-blocks may have slightly dried as well. I’m sure that I’m over watering now. Everyone says, less is more… don’t over water…. Only water when bone dry…. Over-loving them can hurt the progress. So, I’m going to hold out for a couple days and see what happens.
Placed double doors, with slotted vents from top to bottom, on the closet. Everything still stable.
At end of day it looks as though the Deleted Scene may be poking through the rock wool in the gro-blocks.
Day 3 - Germination 3 [Sep. 8th 2022]

Light Cycle: 18-6

Identification – bamboo = Glueberry OG, plastic = Deleted Scene
WE HAVE VISUAL CONFIRMATION!!!! HELL YES!!!
The Deleted Scene strain has popped through with strength and vigor! Very tall single set of cotyledons!
Worried about Glueberry OG strain since it’s not showing any signs of germination. Going to show a little more patience and continue to hold out from doing anything. Not watering, not gonna dig it up, not gonna touch it. Perhaps it’ll germinate within a couple days. Only time will tell.
Tray still has a little water on bottom and gro-blocks look wet still.
Day 4 - Germination 4 [Sep. 9th 2022]

Deleted Scene strain is looking great, getting taller and poking out the first set of real leaves from the cotyledons.
The exciting news is that the Glueberry OG will pop through today! I can see the head half way through the surface.
I know I said I’d hold out on watering for a couple days, not just one, but the bottom of the tray is now dry and can see the rock wool changing in texture. I added about 5-10mL of regular water onto each gro-block.

Identification – bamboo = Glueberry OG, plastic = Deleted Scene
The Glueberry OG has officially popped through.
Tray is bone dry and gro-blocks are pretty dry to the touch. Seems as though without the dome lid and the lights at 32” above blocks, the plants are taking to it well, but the water dries up within 24 hours. Will water again today, but THIS TIME…… with RO water!!! Woot woot!!
I installed the RO filtration system. Refilled the humidifier and will only use RO water continuing from here. RO water will fill their individual reservoirs in the future. RO water will be the vehicle for the plant’s nutrients as well.
I want to start a very VERY like nitrogen rich nutrient feed while still in the gro-blocks, but a little scared to burn the seedlings. So going to think this over and calculate an extremely light dose. Less is more – right?
Waiting on Gnarly Barley to create sprouted seed tea (SST) for feed as well. This is soon to come.
((WARNING!!! - THE SST FOR HYDRO DWC WAS A HUGE ROOKIE MISTAKE!! I DID NOT KNOW WHAT I WAS DOING - WILL GET INTO REPERCUSSIONS AND SPECIFICS LATER IN SEASON!!)) - Or perhaps, I just didn't know HOW to do it for DWC... idk, will be a question I post later

Today, since the seedlings have been above surface for over a day, I changed the climate in the tent. I changed the inline vent setting FROM 1 TO 2 during the day and 1 overnight (when it’s tent lights out). I changed the clip fan setting FROM 4 TO 3 all day. This has stabilized the tent at 74F and 64% humidity. With the HIGH TEMP: 78F and HIGH HUM: 60% for both inline and clip fans.
Really itching to start Nitrogen rich supplements, but my brain says it’s better to wait until I get them into their final 5 gal pots with a reservoir and top watering.
Initially the Deleted Scene strain really took off to the sky and the floor tray! The first root popped through the bottom of the rock wool almost instantaneously with the elbow popping out of the top. Since then, there’s been no new roots through the bottom, but it’s still stretching pretty well. Has me surprised the root system hasn’t taken over the bottom of the gro-block yet.
The Glueberry OG is taking it’s sweet time just being a slow grower, but thicker and greener then the DS strain was at this point. Very interesting to see the genetic differences.
Going to keep them in the tray until the bottom of the gro-blocks are showing a more pronounced root system, that wat when the water wicks up from the hydroton it’ll be watered successfully. No need to rush, plants still look happy on tray.
I’m thinking the pure RO water just by itself may not be the best for the seedlings in the tray. All metals, micro, and macro nutrients are removed. It may actually be stunting their growth. Considering adding Cal Mag into 1 gal and using that for feeding. Regular faucet water with it’s myriad of molecules will a least provide the plants with nutrients along side all the bad.
Finding that the inline vent on level 2 is too much. Humidity dropping below 60%. Going to run inline vent at level 1 until needed to raise.

“More money = More problems”
Trying to express that the more knowledge I receive about growing in the tent, the more problems I have to solve.
Just discovered what VPD and DLI are. As well as ideal environment setting for specific PAR, VPD, and DLI goals. Grabbed visual graphs from Build A Soil. Will be adding VPD stats and DLI to the daily journal.
As it turns out – I was very lucky with the germination and beginning seedling setting. Only paying attention to temp and humidity with light on lowest setting and far away from seeds. Kept the tent environment in a very low (blue per the graph) range of VPD and overall stress while supplying minimal energy for the seedlings to grow. But then my eyes were opened to everything else.
Learned about GPW, as well as, when/how much to increase light strength. Attempting to increase the light intensity to 100% (10/10) and to 36” above canopy has thrown the entire tent’s environment out of wack. It was easily a domino effect. Increasing light intensity has increased tent Temp to about 84-86F, which kicks the inline vent fan on, which then lowers humidity severely to 50%. The high temp and low humidity brings the VPD to 1.8!!!! Goal is to have Temp 70-80F, Hum 60-70%, with a VPD of 1.0-1.3 range for seedlings. Haven’t calculated DLI yet, but the goal is be at 23 through veg stage.
DON’T GROW THE FLOOR!
DON’T STRESS THE PLANTS!
SUPPLY PROPER ENERGY AND ENVIRONMENT BEFORE ADDING NUTRIENTS AND WATERING INTO THE EQUATION!!

Playing with the environmental settings. Trying to dial it in the sweet zone has been hectic and frustrating. Damn near impossible.
It looks as though by having no control over my temperature, that’s my weakest link. I set the inline fan to kick on every time it hits 84F, because the tent never really gets higher 84 or 85F. So, humidity will stay up. With being over the high of the temperature range (70F-80F) I have to counterbalance that by being over the high end on humidity (50%-70%) at 73%. This at least keeps the VPD down below 1.3. Actually, VPD is closer to 1.05. So awesome. We’ll see how this works out in regard to the plant’s grow rate and bud rot and mold, etc.
I added in another 6” clip fan in the tent (now with two clip fans), to help with temperature and humidity. Placing them in front of the air vents at bottom of tent. I am trying to promote a stronger passive intake of fresh cooled air and CO2.

- Inline vent fan – HIGH: 78F, HIGH 78% humidity
- 6” fan - HIGH: 78F, HIGH: 70% humidity.
- moved all the way to the bottom passive intake netted vent. This acts as a passive intake to pull in fresh air and lower/stabilize humidity. Set 6” clip fan to setting 3.
