plzzz help me!!!!!

ok so im growing in the woods in 5 gallon buckets in big palmetto bushes. I have one plant in each bucket im at like 10 plants now. I have all my stuff in the woods even the water bottles and the M.G and the budding formula. Ne ways im growing them naturally letting nature do its work. Its raining everyday and there all under 5 inches long so i dont water them at all yet,But i do have like 6 gallons of water out there in case it doesnt rain for like 2-4 days. It rains everyday so i dont have to go out there to water them but i liek to look at them and see there progress(who doesnt). More information about these plants are if its light out no matter wat time it is the plants r getting sun but its raig almost everyday so that wont matter and there r holes in each of the buckets so they dont over flow.All theplants are very healthy due to the fact that we replanted over and over again just to get about 15 decent plants.

Ne ways my questions---

1.How long will I use miricule grow(till harvest?) grow for and how many times a month?
2.How long will it take for to harvest?
3.Any other tips on outdoor growing will be nice ne thing at all!!
