Here's a valuable tip that very few people mention: Don't drown your plants.
Because this isn't often mentioned in forums, I never knew that tight soil was an issue
not with the Foxfarm I was using (which is pretty awesome right out of the bag, BTW), but was the result of how I was watering my plants-- which is something I never considered & certainly didn't include in my postings asking for help on the forums. But eventually, after years of looking at my Perlite & Vermiculite floating atop an inch or 2 of water, I figured it out:
The dryness & thickness of the soil make absorption slow & difficult, which in turn makes the water pool-up a couple inches deep, in the pot & above the soil. This in turn will eventually flood the soil lower & lower, & the more watery the top of the soil, the higher the light & puffy Perlite & Vermiculite will float up, which of course makes the soil far below become less aerated & more dense. This densely packed, less-aerated soil-- along with your roots properly drying out (to avoid mold)-- adds dryness & denseness to the soil, making absorption difficult, pooling-up the water which pulls-up more Perlite to float atop another 2 inches of water, and... You get the idea.
So, for whatever it's worth... Moving forward, Be sure to let your plants gradually absorb the water you feed them. If you have several growing, this can be quite easy: Just water them all much less, and gradually, and bounce down the cycle of them all much faster, then repeat that for several cycles, so that the first plant you began watering has had enough time to absorb the smallish amount of water you already gave it. The upper & maybe middle soil will be moist anyways, for sure, if not full-blown wet, so the second watering-- and maybe a final third-- will go much faster, easier, smoother, and with less pooling.
The trick is to learn Patience. It's a plant. You have schedules & a life, I know. We all do. But your plants don't. They only have soil, and Sunlight, and you to water them when the rain doesn't. And the rain rarely floods them. So the Perlite & Vermiculite only work when we let them stay in the soil, and that means slowing down and watering the girls at the plant's speed, and not ours. The good thing is, my issue was (is?) just with slowing the frigg down, and accepting that I have to go at the plant's speed. It's easier with
multiple plants, but this year, I have only
one growing, and it's outdoors in a ladybug-filled PVC "mini-house" covered in insect-netting, so it's awesome, but a bit of a hassle watering it in gradual, slow phases. Needless to say, I'm having a dense-packed issue myself (as all my Perlite & Vermiculite washed away from my impatient ass), and was going to post about it here in these forums, LOL. So thanks for posting; hope this helps!
