yes a dome with holes, what humidity do you have in your tent now? you want about 55-60% in the tent for your larger photo period & if you put domes on the seedlings & spray water on the inside of the dome & cover the seedling it will raise the humididity just for the seedlings which you want at around 70-80% i like 70-75% or you could spray them with 1 shot a few times a day with your sprayer with no dome, would like to see a picture a side shot & a top shot close up i really don't want to give you any bad advise by having misunderstanding of what you're sayingu mean i put something like a Dome with holes on each of the small plants? and yes humidifier is inside but i cant place it out this is the best setup i can get i can only swich places in the tent it have space
get a couple 1 or 2 liter clear plastic pop bottles & cut off the top poke holes around the botton middle & top & spray the inside place over the plant what is your tent humidity?
