Yes i have been growing for about a year now.And when i started i came here and got alot of great advice.And things have been growing way better then i thought.I have grown three different strains.My first grow i used white rhino from green house seeds.Then i grew super lemon haze.NOw im growing vanilla kush from barneys.I am using a 400 watt cool tube.I use gh nutes im using the expert program and i use every bottle.I grow in a gh power grower.I have two tents side by side.one plant vegging and one tent for flowering.I got six and half ounces per harvest.And i got almost 8 ounces from one harvest.Anyways enough of the rambling.My question is if i buy a 1000 watt light and use it in the same tent that should double my harvest right?
