yea iv'e grown the jamaican pearl and it needs lots of organic nutes. great sativa high. if thats your thing. have'nt grown the riser. but the pearl is great choice.
I grow directly on top of large two cubic yards compost piles covered with about 6 inches of topsoil. Good to hear she should do ok with my growing method. Ya I like the sativa high during the day and for parties and the indica for easy nights.
yea lots of organic nutes in a compost heap the j,pearl will thrive and the hot sun will produce huge amounts of resin. making me drool just thinking about it.
