Do-si-dos photoperiod seedlings growing very slowly

From a fellow grower: My 3 remaining sprout seem to be growing very slowly. They were started first week in May and next week will be almost 4 weeks and the sprouts are barley one inch tall. I am only watering (misting) every 2-3 days and doing in early morning and early evening with just the top 1/2 of soil getting moist and completely dry in about an hour. This is an outdoor grow here in Phoenix Arizona. And I am also using the recommended soil (Happy Frog) amended with powdered worm casings and steer manure. Strain: Dos-si-Dos feminized.
Climate: Outdoors.
Temperatures: Day high 90’s to 100’s during the day, 70 degrees at night
Light schedule: outdoor light from 8am-2pm

A seedling only needs a couple ml of water each day.

The best method for seeing that a seedling has what it needs without risking root development problems is to instead use a dome and to not water the soil at all. Use a clear Solo cup or a cut pop bottle and spray inside of the dome a couple of times each day. The plant can get all of the water it needs via the leaves from the humidity in the dome. Start watering a few ml a day when the plant outgrows the dome.

4 weeks old, even though its 1in tall its not a seedling anymore. How big is the pot that they’re in. I think I would give them more water at this point. Take a solo cup put it over the plant then water around the cup then remove the cup, then wait 2-3 days before watering again. That will encourage the roots to spread out. At 4 weeks there could be a lot of root growth going on and not much happening up above. Especially if the seedling was put in a large pot or in the ground.

Add to this the typical LOW humidity and if you are in fabric pots the dirt could be bone dry throughout. I agree with watering it more than a mist or a few drops. In that arid heat you may need to water it twice a day. Ever considered growing inside?

Your biggest problem right here…


I have spent a lot of time in Phoenix and add in the wind and its a brutal environment.
Its why rock gardens are so common.
