Day 22 (27/08/2021): 4th week of 18/12 starting. Not much to say. I topped earlier (5th node instead of 6th and not waiting the fifth node 's secondaries to develop before toping . I know how JH behaves but not the other strains and I don't want them to grow too tall but rather bushy for the scrog.
Day 23: Watering 0,85L/plant, pH 6,1 with Elycitor 0,6 mg/L and Roots + 0,3 ml/L
Day 24: They recovered from the topping stress and started to grow strongly again. I will certainly put them in their final pot at the end of this 4th week.
Day 25: Played again with big fan leaves to expose secondaries's top.
Day 26: I probably top them again and water before repoting.
Despite I give them nothing else than stuff for soil and roots, because the soil is very rich and because you have to be careful on nutrients with J; Herer... I have one showing slight signs of overfeeding. Well, I'll give her only water next time. Can't think of anything else to do.
Day 27: I'll repot all plants tomorrow.
I'll top them again next week, place the scrog net and start training them less gently to fill +/- 70% of the tent surface before switching to 12/12 ( something like around the end of week 6.).
Day 28: All plants repotted in their 18L pot + watered (4L/plant, pH 6,1 with Elycitor 0,3 mg/L and Roots + 0,3 ml/L).
They really needed both repotting and watering: very developed and..dry roots systems especially for the J. Herer showing kind of yellow leaf tips.
End of of week 4. More work to come with the coming weeks !
Your detailed pictures are incredibly helpful and illustrative. I'm about to try a scrog net for the first time in about a week or so, would you recommend any reading or videos to help? I saw you mention about a 20cm distance between the net and the top of the pot. Is there a specific reason for that distance?
@happykat,One more thing, because you can't decide how long will last growth, because they don't like stress and because they're dedicated to outside grow, I wouldn't start an autoflower scrog indoor. Fems or clones.
@happykat,
Among lots of googled resources I bookmarked this one: www.youtube.com/watch
For the +/- 20cm distance from top of the pot to the net, several reasons:
- You want to keep enough height to place an humidifier / dehumidifier and fan(s) under the net.
- 6 plants in a 4x4 needs 6 18/6 weeks + 2 1st weeks of 12/12 to fill the 4x4 surface if you top twice.
I wait until both main "colas" have 3 nodes to top again above their 2nd node and place the net a. At this point plants 's height is 20/25 cm and lowers to 20/22cm because of the net starting to train them.
Following this schedule results in the 20/25cm height
- Keeping the distance around 20/25 cm helps a lot to control height's plants with the scrog technique. A little bit more and I might not be able to keep at least 50 cm between the lamp and the canopy,
... A little bit less, plants won't grow enough to fill the whole grow surface.
- Not less than 20 cm also because you'll have to do some cleaning under the net before switching to 12/12 and until first pistils clearly appeared => You'll need as much access as possible from front and sides 's tent openings ( I have a tent opening on four sides for this reason).
Also, once the net is filled, watering becomes harder (especially with a tent with only 3 openings), you'll have to water from under the net, 20cm + potsheight isn't too much π
Think well of your plants placement/orientation before installing the net: After your started to move branches above below the net, the pots won't move until the cut.
Make sure that you ventilate properly under the net once your cleaning is done.
You'll have "lots" of work from the moment you place the net to the end of the stretch moving branches and leaves above under the net to fill the grow surface and expose as well as possible as much bud sites as you can.
That said, it's rather easy and intuitive. Once you're decided.. It happens ! And it's really worth: Yeld increased by a good 25%..
Happy scroging π
So good job man. How do you feel with CO2 bag? Do you notice it helps? I'm interested in but I didn't try it. Maybe in future but still researching. What's your experience? Wish you the best of lucks with your grow
@HappyWeeds,Hi, CO2 bags helped when TΒ° went above 28 Β°C and plants grow a little stronger and quicker during veg. I noticed the effects on growth comparing this grow to the n-2 grow ( 2 bags for this one, 1 bag for the n-2), same genetics (J Herer same seeds pack),same light, same soil, same nutrients etc..: Plants are about a week more advanced after 10 weeks of life. That said, those bags are way too expensive and I don't get full potential CO2 advantages only because my air extractor is on 24/24 and I have no idea of he realCO2 level /PPM. I use them mainly for summer with Elycitor for summer heats.
@happykat,Yes it is, more or less depending on the strain grown.
