Being a system engineer, I am always collecting data to increase performance. Always trying to dial it in. There were two test that were conducted this grow.
The first test consisted of
-
two growers
- With the same size tent 5x5
- Growing the same strains/ clones from batch 1
- Growing indoors
- Using octopts w/ same soil sunshine mix#4
- Same number of plants #3
- Same Nutes / TPS1 – Feed the same per feeding directions.
- Same type of LED lights set on 75% - Abriselux A2000 LED Grow Light Dimmable with 5x4ft Coverage and Upgraded Larger Board, Full Spectrum Grow Lamps for Indoor Hydroponic Growing Light with High PPFD (Actual Power 200Watt).
- Both Grows flowered for 8.5 weeks
- Both Grows were wash and then dried till snap
-
Difference Between Growers
- One grower used two set of lights
- One grower (me) used three set of lights
I am coaching a couple new growers a long and one of them is a buddy of mine. When I got my setup he pretty much had me create a verbatim shopping list of what I bought all the way down to the nutes, soil , etc. His grow was about 2 weeks ahead of my batch 2. I said lets compare our yields and figure out if the 3rd light really makes a difference… Well… it looks like it does…
4.5 OZ difference is a pretty big difference in my book. Well worth the purchase of a 3rd light. Running the lights at 75% and not all the way up in freedom rock level I experience no foxtailing and no purple stressed out stems.
The second test was conducted with data from my first batch. The second batch were clones from batch 1 - wedding cake and unknow 2000ish indica.
The difference this time was that I grew 4 plants batch 1. I only grew 3 in batch 2. Batch 2 was out of the ball park higher than batch 1.
If you look at the diagram below you will notice that in batch 2 WC1 is the winner in yield while the other two are around the same yield amount. Notice where WC1 sat in the tent? Yah it had much more room to grow. Makes me think “Wonder what two plants per tents would yield” This would cost more in infrastructure (lights, dehumidifier,ac,etc) but in the end would it pay itself off? I might run this test in the future and see.
Thought some would be interested in this information. If any new growers come across this consider these things.
- Don’t go putting 6 plants in a small space. Do the opposite. Put one plant in a small space.
- Consider using octopots. You will not be disappointed.
- More light is more yield. This is about coverage not brightness though.
