Great product and great company to buy from - grow ace is the best
I’m thrilled with this setup. It’s exactly what I needed for my 48x48x80 tent. I have five plants and about 10 clones under the bulb and they are absolutely green.
Worked like a charm from the get go. Simple setup. I have exhaust fan coming out of the hood and a separate exhaust fan going out another port. This keeps the temp at 70-72 degrees here in May. Perfect. The plants obviously prefer this lamp as opposed to an LED and the energy is actually less. The price is right on the money.
This is a win win deal.
Thanks Grow Ace.
Worked well for getting my vegetable seedlings the proper start for my garden.
Shipping was great product was easy to install, but pop rivites that hold light housing together came apart after about 1 week of use. Easy to fix plants love this light good for 1-3 cannabis plants. Would definitely recommend.
So far so good my plants grow thick and dense with amazing vigor thanks to yield lab!!
