I just can't believe how far ahead PL is. Not only comparing it to the other two but comparing to most autos I've seen and grown. Only 37 days old with such nugs...wow!
Moby Dick Auto, Green Crack Auto, Purple Lemonade Auto - 2' x 2' x 4.5'

Hopefully the other seeds are like this as well! The plan is to try one seed of each (md, pl, gc, cheese, lemon kush) and if I like it, make seeds with the remaining seeds I have. If the other seeds grow as fast as this one I'd be happy!

Nice one. By making seeds, you mean breeding autoflowers with photoperiods? I will be growing 4 FastBuds strains next grow into 4 7L pots as an experiment. For sure, Green Crack, Blue Dream and LSD-25. I can't decide for the 4th one. Mexican Airlines and Six Shooter have amazing reviews and Blackberry has won an first place award. I assume it's gonna be one of them 3.

I was planning on self Pollinating with STS with a small solo cup or maybe 1 L.

Small update. Added another fan last night and spaced out the plants more, but this morning the leaves were droopy where the fan was pointing. Not sure if it's because its drying the soil out or the fan is too strong. Either way I turned it off and I need to get a circulating fan.

Another quick update. Just showing PL without the light. Main cola is just over 12 inches long! Tonight I'll be completely changing up my tent. Changing the carbon filter to pull air through instead of push are through, and change around the intake and exhaust ports for better circulation. PL almost smells like a mandarin orange and is starting to get really sticky. She is 38 days old.

So you have a carbon filter inside the tent connected to an exhaust fan with ducting and the exhaust fan is pushing air out of the tent. That's how most people do it, including pros. I only used carbon filter once, but I thought it would pull out more air if the exhaust fan was pushing air TO the carbon filter instead of FROM the carbon filter. However, I'm not en expert and since most people do it like you, it must mean something. I have asked about this before on youtube but didn't get a reply.
Man, that is a pretty plant! Crazy how far ahead of the others she is.

That is how I had it until last night. I was pushing air from the tent to the carbon filter. If I put my hand on the filter it felt like there was barely any air moving and temps started to get a little higher. I was reading to pull air through it, not push, so I changed it. Good idea!
I know! These strains said they were about the same time, so I figured I could grow and harvest around the same time... now I have to find ways to dry PL when she's Done that wont leave a smell because I was planning on using the tent.. lol
PL is getting more purple, with the end of the sugar leaves starting to turn purple now. It looks like it may have a calcium or magnesium deficiency, I'm not sure. I'm Going to buy some dolomite lime and top dress to try and fix this issue. MD is 40, PL is 39, GC is 38.

Im a mechanical engineer that works in the HVAC field, so I think I can handle this question.
The carbon filter is basically a resistor in electrical terms. It will provide the same amount of resistance installed at the end of our duct, or right against the fan.
The difference is available pressure. The fan is creating areas of low pressure and high pressure, Low at the inlet of the fan, and High at the outlet. The pressure differential from your space to the fan is greatest at the fan. Therefore, you will move more air through the filter at the location where it has the greatest pressure differential (right at the fan). If the fan has to push air through 6' of ductwork before it even gets to the filter there isn't as much pressure left to push air out of the filter. Basically, the available pressure reduces as the duct gets longer.
Sorry for the long winded technical response.

Makes sense, thanks for sharing my friend.

Great response. That's what was happening with me. I had my fan, ~2 feet ducting and then the carbon filter (air from fan to carbon filter, then out). Now I have it carbon filter, ~ 2 inches of ducting and then fan, and then out the tent. Air is being pulled through the carbon filter now instead of pushed.

Nothing major to update. I switched to 20/4 yesterday from 18/6 after doing some reading. I figured I'd try it out. GC and MD are stretching a lot. I'm going to pull them out tonight and do more LST. I'm also going to the store today to go look for some CalMag
MD is 42 days, PL is 41, GC is 40
I kept looking at my thermometer and wondered why it was always showing the same, I was looking at the all time high and low. I just switched to last 24 hours and it's showing 75.4 for both high and low so it just have just reset. I'l keep an eye out for you.

Changed up my passive intake. My wife kept saying she could smell it, but I couldn't smell anything... but just in case, for her I changed the passive intake around. I had a 15in x 6in mesh screen hole, but now I covered that and put a pair of 4in holes and now I can put my ducts in so I can direct the light. I'm going to move the little black box and have the ducting at an angle.

I moved the plants around to see about better lighting, and I watered with 1/4 tsp epsom salt (magnesium sulfate) per liter of water. I'm not sure if I have a calcium or magnesium deficiency, but I was able to get epsom salt locally so I Figured let's try that. Green crack is starting to stretch to flower, with moby dick coming right behind. I LSTd MD, but I'm going to have to do more!
MD is 44 days, PL is 43, GC is 42.

Are all those plants around the same amount of days? That one plant in the back has great bud formation going and lots of white pistols so she got a waays to go still. But the others dont have much bud formation interesting.. Looking great tho

I germinated and planted all 3 at the same time. Moby dick popped first, purple lemonade the next day, and green crack the last. PL started showing preflowers about 2-3 weeks before The others so she has been going quick! I thought that I could do 3 at a time and harvest within a few days of each other... I guess not... lol.Are all those plants around the same amount of days? That one plant in the back has great bud formation going and lots of white pistols so she got a waays to go still.
