Second grow - Sour 60

[Cal X]

You should be able to vent in cool air from the hole that you cut in your A.C, the landlord won't like it, if you're renting, though! Just put a spring loaded damper on the venting so the smell doesn't back up into your A.C when it's not running! I had a high % of males once during a hot run, best to not take chances.

I have read that keeping temps below 80 can cause a higher percentage of females.

I've read similar about temps and humidity, that's reason enough for me to go with feminized every time. Worst case scenario, a hermie, which can be fixed with moderate ease.
Nothing wrong with growing temps in the upper 60's to lower 70's, I just prefer to grow in warmer/humid micro-climate (78-84F).
I was wondering if the plants are supposed to be so small after three weeks? With approximately seven weeks remaining, max five with nutes (you are flushing for at least the last two weeks, right?), kinda makes me wonder if these plants will produce anywhere near 40gms. Time will tell...

Good luck...
Happy farming...

There is significant variation in size from smallest to largest. If they need 70 or 80 days because of the slow start that's fine, wonder what I'm doing wrong that some of them are so small?

Continuing to read on sex, there are also those who say sex is determined before the seeds are planted, and that you cannot influence sex at all....so who knows???

[ZBeebs]

It actually seems as if most people think that sex is pre-determined, and nothing I do will affect the ratio of males vs females. Jorge Cervantes does say that temps, among other things, affect the ratio, but science seems to disagree.

So I've had it running at 600w for more than a day, and with the lower vents open there was no change in temps. I've tried a couple other different variations, but the one that helped most was I added a small fan outside the tent blowing in, and now it's reading 79.6. Those temps are fine with me.

I think the reason they may look small is I have started counting from the day I put the seeds in soil, and they took a while. Some of these didn't break the surface of the soil for 10 days I think. If you don't count waiting for them, they are only 11 day old seedlings in those pictures.

[Uncle Ron]

Mother Nature, what a bitch.
There's a lot of info about how to influence the sex of the plant, and come to think about it, there's even some for humans, go figure.
There may be something to all of this, then again it may all be BS. Who the fuck am I to argue with Jorge, scientists, or Mother Nature? As I stated earlier, this is the main reason I choose feminized over regular. I don't want to invest resources, to which time is the most precious to me, on growing plants only to discover that 7 or 8 out of 10 are males. That's just me, kind of like to each their own and all that...

Strange how opening the vents has little effect, although 79.6 isn't bad. What is the rating on your exhaust fan, as in how many Cubic Feet is it supposed to remove per minute? As you remarked, maybe setting a fan on the outside of the vent might help, sort of like a push/pull method. If you are able to relocate one of those black fans clipped on the tent poles to the inside of one of the vents might do the job, maybe.

As for the size, I had to go back and re-read the beginning to see that the seeds took a while to sprout. Given this little tid bit, I now see the light...
Good luck and happy farming...

[ZBeebs]

The main exhaust fan is rated at 200CFM, and it's a quality unit (Vortex), not an eBay special. I have three clip on fans in the tent, two of them oscillate, as well as a fan outside the tent blowing into one of the lower vents. Temps in the tent are 79.6. Temperature just outside the tent is 72. Would like to get more of that 72 degree air into the tent, but not necessary...will continue to experiment with fan placement and venting...but 80 degrees should be fine.

I have been moving them around the tent so they take turns being directly under the light in the best spot(s). Every two days they move to the right, with #10 moving to the #1 spot. A couple of the plants are showing some deformities on the first true sets of leaves, which I've seen on other Sour 60 grow journals. I can take better pics of the irregularities if anyone is interested.

The pics below were just taken, at 25 days since the seeds were planted. They sprouted anywhere from 15 to 20 days ago.

I have been watering them about every day and a half or so, a gallon total in the ten pots. I watered today and added 2 tsp of Pure Blend Pro grow solution. The bottle says to feed 1 Tbsp during early vegative growth, and that is what I will do next time they are watered. As long as they show no signs of nute burn, I see no reason not to feed at full strength according to the label...and it says to use every time you water.

They look good, ZBeebs, nice growth since the last pics!

[ZBeebs]

It is 28 days. or 4 weeks since I planted the seeds. They sprouted between 18 and 23 days ago. One of them has shown sex (#5) and it's a girl! I'll be keeping an eye on them to make sure no males get to stick around...

I've been feeding them a grow formula, should I switch to the bloom formula now, or wait until more of them show sex?

Here's the pics...

Can you not give a mixed feed ? Veg n bloom ? Wi biobizz you continue giving veg nutes for a week or two after you introduce bloom formula

Yes. I just read the directions and during transition the directions are 1 Tbsp each of Grow and Bloom.

However, I have not fed them more than 1Tbsp per gallon yet, so today they will get 1Tbsp of Grow, and 1/2 Tbsp of Bloom, and next time I will adjust in the other direction before going Bloom only.

I also think I'm seeing my first male...will post a pic, want opinions before I kill it...

[ZBeebs]

This is plant #6. Is it a male?

[archambaut]

Looks that way, though no harm in leaving a few days to be sure.

[spireax]

as above, but I reckon you'll chop it pretty soon, if it shows both sexes you could pick off the male parts but the plant don't like it, you can easily misss a few and ruin the crop and as you've got a few plants I don't think you need to.

[Midzy]

its a boy

[Midzy]

kill it
