have 2 frowned upon 300w galaxyhydro LED lights 1mo into vegging 12 plants. I did one blue dream plant w 1 of these lights and was told it hurt my yield (2.25oz). Not looking to waste time with 12, clearly I need more watts. I am prepared to purchase. I have space for no more than 2 more lights but ideally only 1 w high wattage. Not looking to spend tons but after reading more on galaxyhydro pls help! Thanks Nug.
