There is another one on ebay besides the used one you bought. I have seen one go for 725. But the seller repost due to identity fraud by a bidder, it then resold for 650 I believe.
Stealth, I just came across your excellent LED grow last night and read from start to finish. I have 5 procyons on order due in this week and have now got wood thanks to your post. Would you have rather seen your test than greenpine on that sellers sale?Can be done!
