I got the Growealth G3000 with your discount, THX. I have some Bruce Banner Auto ready to go like tomorrow. I would still appreciate a beginning height, and dimness, and should I put the UV to work now or soon? IR later I assume? Would your UVB bar work above a board? like this and should I move to bars and a higher hanging UVB bar like yours anyway? Want to go to NFT, what then? Soil from the nearby forest for now because money is gone. Trying to get the nutriculture people in the UK to chatter with but no go, so far, I’m in the US – do your prices reflect a VAT we pay also, or what do I pay for an Array Pro? – even though my people came from Wales. . . Although as I understand it, the English bore the displeasure on the borders of Wales. We stole their women and we LET them steal our ugly ones – the way I heard it. – lol – Isn’t that why Elizabeth the 1st had a problem with Mary, Queen of Scots? Your ladies were just prettier also? (I am trying to talk my Hydro Shop into carrying a line of grow lights) I give an extract class there.
