Welcome @mujtaba good luck on your endeavor. Growing Marijuana can teach you a lot about life and can be very rewarding. That cashcrop4 might be what you're looking for but I'd research the shit out of them and see what people say regarding similar set ups for a comparison. If it was me I'd look for one with two chambers so you can veg and flower at the same time and have less time between harvests. Might cost more but the rti would be worth it. You can always build one, tons of write ups on the subject. Any question you have has probably been answered on the Farm, search feature will be your best friend and save time waiting on replies if your in a hurry. YouTube is great too. Hope this helps you out.
