In comparison, the plants indoors have directional, overhead lighting from fluorescent and halogen lamps. And, the temperature does not fluctuate much. I can't mist the plants inside without the danger of causing damage to the yellow halogen bulb. It's too expensive to risk shattering it. Oh, and the indoor lettuce was decimated by aphids. Bugs in my house? Ick! I was not expecting that at all. Luckily, the aphids only liked the lettuce and stayed off everything else. I am very grateful for whatever creature is eating aphids out in my hoophouse.
When it comes to the bok choi, the plants in the hoophouse are growing faster. But, the plants inside are a lovely deep green = more nutritious. I have slugs tasting my bok choi outside too. So, the aquaponics system under grow lights wins for bok choi.
The tomatoes and peppers seem to love being inside. I am also starting some new plants (parsley, basil, summer squash and butternut squash) in Jiffy-brand peat refills stuck into net baskets full of hydroton.
The center of the pot originally had a Chinese cabbage growing there when the surrounding lettuce were small. The cabbage has since been harvested. This is my version of crop rotation. Or, should I call it succession planting? At any rate, I let smaller plants grow in the protective shadow of larger ones. When the large ones are grown out and starting to bolt, I harvest them and replace with a small plant or seeds. By then, the smaller plants nearby are large enough to protect the new ones.
(p.s. That is last year's chocolate mint sneaking up behind the pot. It somehow rooted itself under the flooring of the hoophouse and it is breaking through. Gotta love happy, hardy plants.)
(Note to self: take the time to weed the hoophouse before taking pictures to show the world. Sigh.)
Oh, and it's pouring rain outside but the soil in my pots is dry as a bone. Turning on the sprinkler now. That's the only downside of growing inside a hoophouse -- no free water.
