Growing on a horse farm..need tips.

Ive grown indoors for a couple years and I have 5 strains going, all in clone mode.

In the next couple weeks I'll be taking a handful of clones that will be transported (eventually) to a friends horse farm.

The soil there is pretty clay (but not awful). My friend has suggested mixing in aged horse manure.

My plan was to keep the plants in pots so they are mobile (and not susceptible to the early October storms we tend to get)

So, anyone with horse manure experience, can you share your experiences?
I'll have to take my PH tester out there soon to get a better read on the soil.

Horse manure is very effective I use it my holes. Just make sure it is fully composted. Also a buddy of mine said to watch out for any wood chips/bedding made of wood which could carry plant disease. Mix it in with some decent top soil, some perlite, dolmite lime, and peat moss and you'll have a nice little cheap mix. You can buy big bales of peat moss from walmart for $10.

Friend says all the manure in a certain field is 8-12 months old.

Planned on mixing it with some FoxFarm planting mix.

That should work just fine. However horse shit does compost better in piles. I have a three to four year pile of shit lol. The bottom of it has the best stuff

I have a horse farm myself and use the manure all the time in my gardens and plots, make sure it is from a compost pile when you dig it so it is rotten not too "hot". The only other issue is weeds because horses don't have the multiple stomach advantage of cows and dont digest the weed in their food before sending it out the waste chute, lol.Good luck.

Turns out there's an old worm farming patch of land.. got some very dark, rich soil from the top 6 inches of it.

Need to get a calibration kit for my PH meter though..

I'm wondering, im in ky too....what part are you in?
