This is my idea:

Let´s say 1m 12 clones same strain on same soil mix.

6 grown with plain wáter
6 grown with wáter&liquid feeding
Differences in production / quality/ cannabinoids

Here's what's on my list for side-by-side grows. I built this cab with the intent of doing some side-by-side grows so everything is exactly the same. Same light, same ballast, same exhaust, etc. It's likely that I'll be building a larger version of the same cab as I'd like to run 600's instead of 400's. The following are what I intend to run in my CURRENT cab under 400's.

Defoliation - already began. Will be doing this in ONE cab, may repeat using two separate cabs. I'll be ensuring that the non-defoliated plants do not shade out the defoliated ones. 2 strains, 4 total phenotypes. The reason I'm only doing this in one cab, is because one side is currently a perpetual SOG with multiple levels (pic is old) and was only in mid-flower when the cab dedicated to this test was emptied.

CMH vs HPS

Vertical vs Horizontal - this one may be harder because 1) I don't own reflectors, 2) I imagine the environment will differ given a hood is essentially a radiator that holds heat and the duct runs will be different. I'll see if I can't get it done, though.

I'm not sure if side by side comparison grows are the real way of determining actual useful methods for our hobby.

For example, if we took the top 5 requested experiments we would see variables that we can't account for.

1. defol

2. distance

3. nutrient test comparison

4. sugar or no as a finishing agent.

5. temp


IMO, each is highly subjective to the genetics at hand. Even then, we can't be sure of the methodology of the person who is actually conducting the experiment to understand the difference between generations amongst test subjects.

Testing penetration of lights, flow charts for new set ups, those i can see happening. Thats the kind of information that can be replicated in different environments.

I think until we get to the level where we can better understand the physical components of what make up a plant and the genetic nuances, all of these tests will be only applicable under the exact physical environments they were tested in.

What I mean by physical components are identifying strains other than their THC/CBD content or leaf structure. Whats the internode distance, length of branching, stem thickness, water retention.

What about for each plant having a base measurement of:

1) intake of CO2
2) production of O2
3) the production of carbs
4) Measuring the increase in dry/wet mass

What is the base pot size used for all testing? Are we assuming that all tests are indoor tests?


I am all for more testing and more research, please don't take away from that wall of text that I'm playing devils advocate just to be d*ck.

All I'm really saying is that there should be parameters for ALL testing before we even start to discuss what to test.

Have a great day guys.

here's an idea -
12/5.5/1/5.5 (DLI it is called?)
vs.
regular schedule

i'd do one myself if i could but i really am can not .
be more than happy to see one though .

[GanjaplantaSTL]

Someone please side by side with DUTCHPRO nutes and advanced would like to know if there's a difference.

Getting ready to take delivery of all my goodies, its my first grow and I want to get it as close to right as possible. Advice Welcome.

- BC Northern Lights - BloomBox
- BC Northern Lights - Mothership
- Titan Hyperion 1 Atmospheric Controller
- CO2 Regulator/Tank
- Battery Backup (Working on a homemade version, amazon has great deals on SLA batteries with high AmpHours. I converted my sons powerwheels from a 9.5 AH SLA battery to a 26 AH Rhino SLA battery and it was super inexpensive)

I'm using my closet to hold the boxes. I decided to get a rolling 12,500 BTU AC/Heater to run independently, cooling and dehumidifying only the closet, hoping that keeps temps inside the boxes consistant. Maybe it will save me a little power by not having to cool my whole house all day too. Since I was on a spending spree I went ahead and got a Oreck Air Cleaner too (total over kill, but wtf its my new hobby). Just got done ripping the carpet out of the closet and installing hard wood floors. Hell yeah, ready for delivery.

Autoflower on 12/12, 18/6 ,20/4 and 24/0 light regime could be great

[Hen]

Has anyone tried 2700K white light LED vs fairly professional blurple brand LEDs with the same wattage.

[doams]

got this idea:
two plants same strain same size pot same lights same nutes

question:
one plant will be topped just once other one will not.
will the topped plant yield twice as much dry as untopped?
