Light cycles are something that are really manipulatable for experimentation in growing, and for that i am happy because it makes for very unique adaptations of conditions and an ability for growers to try different things. To each his own- let us all share our stories of success and even those of pitiful failure so we can learn from eachother.
I believe on my next grow I will go 18/6 straight thru and do half in 36 darkness half in not- and see what happens- I did a lot of playing with lighting this time- so i have all sorts of variables
Thanks to the cool breakdown on the light-
btw you have some serious light cranking 2000 watts damn!
HI guys hope its ok to join in the thread,
I must say reading helpful & direct information from experienced growers like yourselves is a god send. All too much nonsense to handle sometimes. I am a new 1st time grower indoors but have invested heavily in research and my 1st set up & also love for Cannabis. I have a 60sq foot tent with mylar inside, Ventilation & humidty is very good with lots fresh air/exhaust & no real temp issues,
4x600W cool tubes Digital Ballast 23-30% more intencity, 51000Lum MH during Veg and bout to switch to 80k lum HPS after 2 weeks initial flowering Plus add 1 or 2 more 600's for flowering.
Began with 18/6 Light cycle from 1 week old clones (not sure of Strain but looks a hybrid) to 2 - 2.5 weeks then upped to 20/4. I am into my 6th week of Veg & have only just installed my SCROG Screen just at the top tips. I have topped 1 of my ladies, 1 left natural as it spilt at 1st node & 3 have been FIM'd approx week 3 of veg. They are very bushy and have multiple branches & bud sites, overall size is roughly 2Ft high/wide.
I am going back to 18/6 for 2-3 nights then 14/10 for the rest of the week to slowly reduce the light cycle in turn propoting strong final growth then will try a 24-36Hr complete darkness (wearily as I do want them to strech above my screen in first couple wks) then to 12/12 & may throw in a spell of 13/11 during weeks 4-6 of flower to see if I can really maximize yields.
This is all very new & Exciting to me but having Forums such like these are very useful if you can decipher good info through the crap, place some of it into practice hold on & hope for the best.
If any one finds this interesting I am willing to post some pics but like I said I am fairly new to this so be patient.
Stay Safe & happy cultivation
