low yields

[Ptmarkg]

I grow in a walk-in closed, 9x5, I use plat pro leds, keep proper ph levels for nutes and water, humidity levels are proper for veg and flower, canopy is made level by lst, temp is in mid 70s. I use the suggested nutes, I do not have air flow. When I get home I open closet door and use fans to blow fresh air in and out. Seeds are mostly Nirvana fem. My yields are a little more than an oz per plant. Is air flow my problem?

Hi Ptmarkg, I'm a new grower so take my advice with a bit of salt.
What's your light source? How many watts? Air flow helps, but its not mandatory (I know of some people who grow without proper air flow, just air renewal like you... Their main problem is the bud becoming too heavy for the stem haha. Air flow is supposed to strengthen the stem, among other things.)
Why not buying a very small fan, or a desktop computer fan even, and rig it inside the closet, if you think air flow is the problem.

Seeing some pictures of your set-up and plants would help a lot in trying to figure out why your yields are low. What size is the Platinum Pro that you are using, how close to the plants is it and how many plants are there? I have a Platinum Pro light and use Nirvana auto for my last grow and had what I thought was a good yield of 6+ oz from one plant.

Howdy Ptmarkg and welcome to the forum.
Because cannabis is an air pollenated plant, air flow and circulation is very important for the plants proper growth and bud development. You need, at the very least, an oscillating fan in the grow area gently circulate the air around the plants and bud sites for the best production.
Good luck on Your grow.

Sorry, I forgot to mention, my grows are in a closet as well, 2ft X 6ft X 8ft tall and I have two (one at each end) 8" oscillating fans and one 6" exhaust fan at the top to get the hot air out. I am running two CFL lamps with 220 watts each. I use DWC.
