In 3 weeks they should be doing good for size and able to take more water in pot. So I would water and cover pots with saran wrap set where they will get the best light and go.
I am curious if you have plans on getting a grow light. I have to ask because they will not do well inside with only the light threw your window or the natural lighting of a house. Cannabis needs a specific light spectrum at higher intensity than that can provide.
I will do for sure. I plan to order in 1-2 days so when I come back I might have them delivered. I asked in another topic about lights, will be glad to hear your thoughts as well. My budget is $200 max unfortunately.
When you go away I would give them a drink before you go and leave the light on 24/7 while you’re away. They will be fine for 5 days in those pots and they should grow during that time.
Back im my pet fish days, when we acclimate new fish. We would use a airline and a water bottle to adjust the water temp and ph as best we could. What you do is poke a hole in the water bottle top, then stick the airline in the hole. Fill it with water. Next tie a lose not in the air line. Make sure its lose enough to let the water drip out. If done right, you can get 1 drop an hour, to 1 drop a sec out of it. Or you can use a cottonball and a water bottle.
As far as light, make sure to get a timer of some sort as well.
I need to hit this darth vader og a bit more.
