This is my first grow!!! Two ww autos from pyramid seeds in 3 or 5 gall. i have a little greenhouse outside. not the best but its a green house. i got regular potting soil that i mixed with petite. The seeds are germenting inside of jiffy greenhouse pods with a top and a heater underneath. so like a incubator. is there anything i should know about greenhouse grows, what kind of nuts (cheap)i can use to help my yield? how much to water and when? I have done my own researh but just looking for help to get the most out of it.
