Day 36 (10/09/2021); 6th and last 18/12 week starting. Playing with branches and leaves 3 times a day to fill the net.
Day 37 : Same than yesterday.
Seing how they grow, I might switch to 12/12 two or .three day earlier than expected.
Day 38: Same than previous days: branches above below the net and leaves placed to expose future bud sites as much a possible.
I'll spray some neem oil for prevention before the lighe is off.
Day 39: Filling the net, branches above below it's grid blablabla
Day 40: Defoliation under the net on each plant.
Watering 4L/plant pH 6,2 with Elycitor 03, mg/L, Roots+ 0,3 ml/L and Orga grow 1ml/l for all plants but BB3 and CH 1.
Day 41: Watering 4L/plant pH 6,2 with Elycitor 03, mg/L, Roots+ 0,3 ml/L and Orga grow 1ml/l for BB3 and CH 1. The4 plants watered yesterday reacted very well to the low dosed orga grow.
I'll switch to 12/12 at the end of day 42,...Tomorrow ! The stretch will fill the middle part of the net and I probably let grow earlier on its sides.
The day after tomorrow TΒ° will low down by 2Β°C and another 2Β°C for the rest of the month => The TΒ° will be perfect in the tent for flowering and I'm going to lower RH a little from tomorrow.
Day 42: The light will be off 6 hours earlier => They had their first 12 light hours followed by a 12 night hours.
I cut a few more leaves and branches and will let them quiet for a while. They all look good and the stretch will easily finish to fill the grid.
End of week 6. Part 3 starting !
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.
