I’ve seen people with spider farmer and these I got a cheap 2x4x5 off Amazon I did get what I pay for with some fixable light leaks but it’s pretty cheap plus it’s put in my closet so light can’t go trough the venting. I’m definitely gonna upgrade with a new job I need a flower tent ima just use this for veg but it is kinda big for that so idk honestly
Light - https://www.alibaba.com/product-detail/Meijiu-Samsung-lm301B-240W-QB-288_62357806206.html?spm=a2700.galleryofferlist.normal_offer.d_image.6bc0522e5ToRSV (Get 3500k option)
Overall this is on the smaller side of tents, but if you get good you can yield a LB or more. Total cost = $232, above budget, but much better.
Alternatively here is a kit that is $10 more than your budget. The one in your link, it does have a blurple light, but you can certainly start out with that. The tent is probably better quality as is the blurple light than the alibaba one you posted though.
if you need a tent, this is good one for the price
