No matter how many Growers Slag Mars Lights ,I can't fault it its done me good over last year ,Been a Plant in there on Flower every 8 week .Apart from when i first got it ,then i wanted to start one from start to finish ,And have to say the Plants really did well under it vegging wise,And flowering .Since then i have just flowered ,It not the greatest light for getting massive weights ,But the least it has done me is 4 oz ,The most 1/4 under 6 oz dry weight .Cost of running this Tent is very low ,so for some one on a Budget,Lets face it we all are really it would be a great light to start of with.The Blueberry Gum seems to be liking the Room and the light ,lets hope this one does a dry weight of 6 or more Doubt it will do more ,But 6 i be happy with ,This plant is a real little bush .I hoping during the 4 week stretch ,it keeps the close node growth .G13 Labs ,is a seed breeder that i have only started using in the last couple of year ,and i'm yet to do a bad seed from them.After the bg is done i'm gonna put the Blue Lemon Thai in,Then move over to a light that everyone seems to be going on about on here cob ,and look the dude up that builds them,i will be chuffed if i can get a low cost running light ,that producers the same weight has a 600 watt hps ,I only do 2 plants though ,so a lb per plant dry and i will move over from hps to something new.
