I have found that some potting mixes contain redwood. Is redwood really that good for a soil mix? It stinks like redwood soil very strong after filling only 2, 5 gal buckets with miracle grow potting mix, which contains the redwood. I didn't want to get miracle grow, but it was the best Walmart had at the time, so I figured I could try one bag of it. Now I regret it simply because of the smell. I have young hashberry plants in veg that have a very nice aroma, but it gets fouled up by the redwood smell
