Transition Outdoor Light Cycle

Okay I have a question for some of the experts. Please if you don't have personal experience keep your uninformed opinions to yourself.

Last year my seeds got seized at the border. I live in Colorado and I am legal so that was rather annoying. Anyways I had to scramble last minute and get some clones. I didn't want to put all my eggs in one basket so I got clones from two sources.

One set of clones were fairly fresh cuts (still in the cubes) and did great with their transition outdoors. I slowly hardened them off after transplanting them in soil and the rest is history.

The second set of clones were a bit older (roughly 1 gallon pots, 1 foot tall) and a couple weeks after I put them outside they began to flower. It wasn't until mid season that they finally turned back from veg and it definitely killed some grow time.

I am not sure if the second set that flowered early was under 24/0 or 18/6 when indoors. Either way I want to avoid that problem this year.

In a week I will be sprouting my seeds indoors to get a slight start on the season. From the literature I have read, some people are saying to start 18/6 but then slowly work your way down 15 minutes each week until you match the light hours outdoors. In my opinion I feel like this would signal the plant to flower.

The only alternative I can imagine is starting the plants at 14/10. Does anyone have experience with a light schedule like this? In Colorado that is the amount of time the plant will be in light in May when I move them outdoors. I don't want my girls to flower when I move them outside I still want them to veg for longer.

The location doesn't have electricity so supplemental lighting or interrupting the night cycle would be difficult.

I found this literature from Jorge Cervantes:

How to safely move plants outdoors?

You have two options (different options to start growing outdoors):


1. Start growing your indoor marijuana plants as usual – in a 18/6 cycle – but waiting until the end of June to move them outdoors.
-doesn't work in my situation because I want to put them out in May


2. Start growing your plants indoors while following the outdoor natural photoperiod. For example, if there are 14 hours of light per day, give your plants 14 hours of light per day as well. When the natural photoperiod increases to 14-15 hours of sunlight per day, you will have to set your timer and add 15 minutes of light per day.


This very straightforward technique will allow you to move your plants outdoors in spring!


This information seems to imply that yes, I would be safe vegging under 14/10. Does anyone have information they can add or what they do? Cheers!

You should be fine putting them out in the middle of May or end of May. I know Coloradie is still somewhat cold then though isn't it?

Yea last frost is usually around May 15th or so. I usually put them out around the 20th-25th just to be safe.

Like I said though last year some of my crop started to flower early June so I am worried about the plants flowering too soon. I want to do the 14/10 light cycle to be safe but I want some feedback from others before I go this route.

I use a 14/10 cycle on my seedlings starting in March and begin bumping it up about 15 min a week around the 3rd week in April. By the middle of May your good to go. I always set mine out under cover though, it might not stop raining here until June.

Sweet thanks slow drawl I appreciate your insight!

Yea I got a greenhouse for protection luckily. I did the unprotected outdoor thing for one year and got destroyed by some crazy hail storms and early snow. :/ After that I knew I needed to save up and invest in a greenhouse. Thankfully still managed to duct tape a majority of the plants back together and get a harvest :lol:

I never had this problem with clones in previous years so that's why I want to be extra careful in avoiding the early flower this year. Especially since I spent a lot on my seeds.

I definitely plan on slowly adjusting them to the sun though, made that mistake before too lol one year I had to bring some girls back from the dead by spraying them with mist every hour:wall:
