Fall soil preparation

I havd great sandy loam. In Oregon Willamette Lley ( mild weather with 3 months of good sun.I dug a 2 ft deep by 3 feet hole and used some of the loam, 10 % pearlite 2%line stone. And 80% mulched maple leaves. 8% kitchen compost. Should I add bannanas, kelp, eggshells, steer manuer now to let the mixture decompose over the winter. I plan to build a 3 foot by 3 foot box 2 feet high and fill with this compost mix to alow soil to warm in spring. I will be growing g13 lab pineapple express.at else should I add to this fall outdoor prep hole and raised box. Also what can I add prior to moving from indoor veg room to out door grow spot in April.

You're making this way too complicated and putting too much effort into it. I'm a simple man - upcan your plants to black commercial 3 gallon pots with 6 drainholes and when ready to set out in the spring dig a 3" deep hole with a shovel. Remove the drainhole plugs (I use old foam) and drop the pot in and cover the sides with soil. The roots will grow into native soil which you need not amend. Search out my posts, I recently posted pix of the rootballs. https://www.rollitup.org/t/giving-defoliation-during-flower-a-try.839655/page-73#post-11069224 I use a 12 month slow release food.

You MUST acclimate your plants to full sun or you'll burn them up. Starting them off with intense HID will be fine but you need to know what you're doing.

How's security and risk from pests - animals, people?

What are are you in? Dundee Hills (jory soil), Ribbon Ridge, North Valley, Mid, South? There is quite a variation, hence the amazing wines coming out of the various AVAs.

You should add more nitrogen like from blood meal to make sure your monsters have all they need trough the season and warm that pile up since its mostly carbon (leaves) other than that you should be good just use good aerobic teas (vermi is best) and should be a nice season better watch rats tho theyll fuvk with the banana peels and stuff
