Love my new grow tent!

Oh my goodness, I just had to share how happy I am with my new 4x4 Grow Tent! I've been wanting to upgrade for ages and finally did it. The quality is fantastic, super sturdy and reflective. Setup was a breeze, even for me. It really makes a difference to my setup. I'm already eyeing some of their ventilation kits. Definitely going to shop here again, and I've already told my friend about them!

Good deal on FC 3000

I was looking for a new LED light and found the FC 3000 here. I compared prices with a few other places and this site had the best deal, especially after I signed up for their newsletter and got a 5% off code. Shipping was reasonable, took about 6 days to get here. The light works well, and for what I paid, it feels like a really solid purchase. I think I got good value for my money.

Are these Mars Hydro lights actually good? Or should I just bite the bullet and go for a Spider Farmer or something?

N Nina Patel 1 month ago

Mars Hydro is solid, especially for the price. I've had a TS 1000 for a year now and it's been a beast. Good for flowering too.

G Gwen 1 month ago

They're reliable. Not quite Gavita levels maybe, but for most home growers, Mars Hydro is totally fine. I think they're better value than some of the pricier brands out there.

Hey, wondering if anyone knows how long shipping usually takes for a grow tent to London? Need it kinda quick.

E Emma 1 month ago

Mine showed up in like 3-4 days to Birmingham, so I'd guess similar for London. They ship from within the UK, so it's usually pretty fast.

D David 1 month ago

Yeah, I got my FC light in about 3 days. Pretty speedy, they definitely don't ship from China or anything crazy like that.

how easy are returns if a tent doesn't fit my space? kinda worried about getting the wrong size.

S Sarah A. 2 months ago

Returns were easy for me, just make sure you check their policy on the website. I returned a light that was too big once, no hassle.

L Lisa Bennett 2 months ago

Yeah returns were easy, did it last month. Just make sure you haven't like, set it all up and got it dirty haha. Should be fine.

anyone know if the packaging is discreet? Don't really want my neighbours knowing what's up lol.

D Derek V. 2 months ago

Very discreet. Just plain brown boxes, no branding or anything that screams 'grow equipment'.

T Todd 2 months ago

Can confirm, my order arrived in a totally plain box. You wouldn't know what it was unless you opened it.

Got a 10% off code from a newsletter signup, can I use that on an already discounted item like a Black Friday deal?

K Kate Kim 2 months ago

Probably not, they usually only let you use one discount at a time. So if the Black Friday deal is already a discount, your 10% code probably won't stack.

D Derek Brooks 2 months ago

No, you can only use one coupon per order. The newsletter code usually won't combine with a sale price. Choose whichever saves you more.

Thinking of grabbing one of the FC-E series lights, but also want a tent. Any chance of stacking a discount code with a bundle deal?

A Amber 2 months ago

Nah, pretty sure it's one code per order. You can usually get a decent bundle discount already though, so check those out first.

R Rachel Reyes 2 months ago

They only let you use one coupon. I tried using a newsletter one on top of a clearance item and it didn't work. The bundle deals are usually good enough on their own.
