>>1476843I find that it gets scratches, absorbs water through them then rots out. If only one side, the side facing the water, is coated then it can still dry out through the other sides which will reduce the chance of rot. Any sort of plywood or particle board will have issues with swelling and coming unglued.
>>1477025>>1477084I find that mine grow a ton after watering. In an effort to prevent rot I try to let the dry out just a tad, but starting this week I'm watering more since there's more root and leaf space to compensate. Mine are in rich soil, fyi.

>>1477056You'll just need to cover your brassica with insect cloth to prevent that.
>>1477104Judging by the hardiness map (pic) you can grow pretty much anything you want there. Though in some places you'll need polytunnels or greenhouses for subtropical/tropical plants and for plants that need cooler climates you may need a shade cloth.
>>1477227I'm not sure how effective that will be since the white butterfly-like moths that lay the eggs tend to dive bomb and lay an egg while still in flight sometimes. Well, touch down for literally a split second.
