WORM CASTINGS- Alright so the other day i went out to my local HP and found some worm castings. The only kind of worm castings they had was this liquid form that comes in a big soda bottle. The question i had about this was whats the best form of using this type if castings. Is it better to use this to start seeds out. If so how do i use this, do i just treat it as if i was just waterin the plants instead of water just worm castings until its about 4 weeks old? If somone could explain the best way and when to use these castings it would be appreciated.

BAT GUANO- Alright so i order 10 pounds of bat shit the other day and once again im not familiar with using this type of organic substance. The first question i had was whats the best way to use this shit? ---mixing it into the soil throughout the whole grow?------- Use just went flowering by just surface feeding it and then just watering over it?------ mixing it into the soil just for flowering---- Ect..... I think you guys get the point. Im just looking for some advice which would be benifit me the most... because i spent mad loot on this. Thanks help would be appreciated!!
