Autocob from BigSm0. 65 watt k3500 2018
Lighting and cycle will remain constant through flowering

@wes Got it Thanks,

@Mañ'O'Green @davisgirl

Week 6 Update

Day 38 and the second week of flowering. The stretch is slowing a bit (thank goodness). I am keeping the lights at 20/4, but added the UV light. Ppms are about 1000 now because I started to add Big Bud and Bud Candy to the mix. So far, so good!

@Iriee Vibez Logged Thank You.

Thanks. Mine is looking pretty good, but yours is looking GREAT! Some great looking plants in this battle, I’ll settle for honorable mention with my single light and Miracle Gro lol. No way I can match hydro results, so I may need to go DWC if I make the second round. Good luck!

@wes Never count yourself out until the winner is declared! Then if you do not win a spot to move on to Light GOTY then the second leg is your opportunity to do so. Entering battles made me such a better farmer. I have learned so much from everyone who competed good and bad.

I love DWC. If it did not get too hot here in the summer I would grow that way. I just cannot economically or practically control the reservoir temperatures. My fastest, biggest plants I grew DWC. I also killed more plants in DWC before I dialed it in. It was before I found this forum or any forum on the web. AFNs got your back!

UV damage to your eyes is not reversible!

I am not sure what you are asking about light?

I'm just curious if it's the usual route to calculate your light per square foot, and that's what you have no matter how many plants you are growing. Or if you take that number, and divide it by how many plants you have to get the light per plant.
Say 4x4 tent, so 16 ft2. Figure out lumen or watts etc. per square foot. Then if you have 4 plants, or 10, do you take that number and further divide it by the number of plants?
I think I'm overthinking it now...

You’ve got it right, total watts in the tent divided by the number of plants.

Without an expensive Meter you cannot measure PPFD which is the information you need to truly be useful as far as light is concerned. Photosynthetic Photon Flux Density or “PPFD” is a measurement of the amount of light that actually reaches your plants and algae or, as a scientist might say: “the number of photosynthetically active photons that fall on a given surface each second”. PPFD is a ‘spot’ measurement of a specific location on your plant canopy, and it is measured in micromoles per square meter per second. This measurement is expressed by scientists and light engineers as:μmol/m2/s.

I gota tell you I have no idea what my PPFD is because I would buy new lights before I spent the money on a PPF meter. That said I wanted a statistic in this battle that made some intrinsic connection. We pay for our electricity in watts and 60 watts per plant is a concept that is easy to grasp. This has nothing to do with the efficiency of those watts used. The plants at the end of this grow will speak volumes.

I hope that answers your question.

Good info, made me smarter ....

@RivetGrrl @davisgirl ..... If I may offer this for consideration:

Back in the Reagan Years (1980 eat) when setting up a room you would try to run 30-45 Watts, even 50-60.Watts per square foot, then, we had Metal Halide and HPS and Florescent VHO LiGhts .... So a 10x10 room at 40 Watts would be 4,000 Watts or four 1,000 watt lights for the room ...

TODAY with LED and COB and Double End - bla bla bla lights, what counts is PAR Readings which is how much light the plant receives ..... Not how many watts a light fixture consumes .....

To size a room look at manufacturers PAR Footprint charts such as the chart shown on this COB .... https://opticledgrowlights.com/products/optic-1-veg-cob-led-grow-light Scroll down and see footprint chart for x size room .....

Who knows in five years we maybe growing with 25-100 watt lights that are super duper effective in putting out a lot of light using very little electricity ... So Watts, while a measurement, it is not something you wanna buy a ligHt or outfit a room by ....

Hope this helps!

That's kind, but I wouldn't count yourself out, man. rarely does the largest plants win, I heard. Plus, I think the DWC is helping these plants grow faster, not necessarily larger. At least that it what I hope. I do recommend DWC though. It just seems like the best way to get the plants what they need when they need it.

Thanks for the info @MrOldBoy and @Mañ'O'Green ! Got a par meter on the drool list so I can work these watts!

Week 6 update.
Nothing's changed other than the lights being raised a few inches.
Lights (4) are autocobs from cobshop.net (see @davisgirl update for all the details)
If I recall right, I named the shrub by the dehumidifier my battle plant. That's the Short Stuff Amnesia Haze CBD cross in the @Rain Science grow bag I'm testing.
She's around 18" tall.

Fine looking lady Dichoti — great structure on her.

She's starting to smell a little funny, too. Not a normal "weed in preflower" smell.
