Hey all,
I'm wondering if I'm struggling with watering my Air Pots. I'm not growing cannabis but am hoping to take advantage of the community's significant Air Pots knowledge...
I've transplanted tomato, pepper, and basil seedlings in to 1-liter Air Pots until they're ready to transplant outside. The peppers and basil are doing OK, but the tomatoes are struggling with leaf curl and edema, with the severity varying between varieties.
I have "full-spectrum" LED lighting, am doing an 18-hour photoperiod, and DLIs are dialed in. VPD is dialed in. Oscillating fans running during lights-on. Indirect circulating fan always running. Exhaust fan is doing about 12 ACH. Air Pot media is Ocean Forest, tamped in like Air Pots recommends, and transplants were initially watered in with a soil drench of MycoApply Ultrafine Endo/Ecto. Watering with RO water of about 18 ppm TDS.
I'm watering the pots when they feel light. Sometimes that's when the surface is dry, but not always. Trying to be cautious of overwatering but also leery of underwatering given the more open nature of the Air Pots. With ~1 month old plants this works out to be a watering every 24-48+ hours, depending on the size/variety. Poking a moisture meter inside gives me readings of 6-7+, which to me doesn't feel like it needs water but with the smaller "margin" in Air Pots and greater aeration, I figured at least the lightweightness was an indication to water.
For those of you with experience with the smallest 1-liter Air Pots, where there's much less "slack" to play around with, do you wait until the surface is dry to water? Or have other tips? Attached a pic of my tomatoes so you can see the situation. Some have had significant pruning to get dead or dying foliage out due to severe edema.
Had a thought last night that maybe I'm overwatering the plants, but they're not seeing typical overwatering symptoms like root rot because of the extra aeration of the Air Pots? However, in the little 72-cell seedling trays I started them in, I let those get pretty dang lightweight and surface-dried before re-watering them, and they had issues in those, too. So... *shrug* / *pulling my hair out*.
Thanks!
