2nd grow making plans

hey every one i am about 2 weeks away from being done with my first grow.... half of the flowering time was with a 70 watt hps and the second half was with a 150 watt hps which i bought half way through.... I am pleased with the results but I want a little more yield next time am want to know what the best method is to get the most with smaller lights...... I am trying to keep the area small like maybe corner of my closet or something... I am doing this one in a rubber maid trash can but im thinkin i want a little more air flow for my next grow..... thanks for any advice im just lookin for ideas

appreciate it .......

Ventilation helps but the biggest factor with yield is the genetics of the plant and light. You should build a grow box and increase your lights would be my suggestion but if you don't want to do that then try finding a higher yielding plant.

any suggestions on high yielding plants

Just have to look around, most descriptions list yield. Big Bud seems to be the most popular for high yields.

my freind is about to have some giga bud clones ready should i get those i heard they are high yielders
