Growing in Low Light

I have 8 girls outside in a nice spot between 2 creeks. The problem is although they are growing strong they are just not as full as i would like because they only receive about 4 hours of direct sunlight. I was wondering if there were any products that could help me acheive a fuller plant. I was thinking about Liquid Light by dutch master and Bushmaster from Humboldt. Has anyone used these products with success? any other suggestiions? Ive been super cropping and it has seemed to help some.

pics will help indeed

nothing can subsitute the sun. More sun = more bud. transplanting not on option? how about trimming tree branches if thats what is blocking the sun. i had to spend over 3 hours the other day trimming trees

cannabis is a full sunlight plant you wont get the max potential of your genetics

if your questing is will you get at least over an O of bud from the total harvest then that answer is yes

with the conditions you described i would expect anywhere from a half an O per plant to a full O.

the spot your describing sounds a bit like mine actually but i get about 6-8 hrs of sunlight per day. i found a tree branch that i could cut down for 2-3 more hrs of light but decided it wasn't worth all that effort and possible discovery while trying to cut the branch down

I had the same problem last year, The plants did not get very big and I maxed out at 1/2 oz a plant. I guy I knew grew the same plants as I did and got over 1 lb a plant in the sun in his back yard. These were the biggest I have ever seen in person.
