Best LED Grow Light For 4X4 Grow Tents – Full 2019 Review
What’s the Best LED Grow Light for your 4×4 Grow Tent?
The best LED grow light for your 4×4 grow tent will be both lightweight and powerful enough to meet the needs of your marijuana plants. This is dependent on several factors like whether your grow tent can support the hanging weight of your grow lights, and whether your grow lights’ PPFD strength is strong enough to cover a 4 foot width.
We recommend using a minimum 900 watt led grow light for your 4×4 grow tent. Sure, people have grown marijuana plants using 400 or 600 watt lights. But their cannabis plants end up with one big flower on top and nothing worth its weight on the sides or bottom. The Best LED grow light for 4×4 grow tents is 900 watts and above, in our opinion.
A top heavy plant with no flowers on the sides, like the one above, is not an efficient use of time or money in our opinion. You’ll be missing out on 30% of your harvest. Stick with 900 watts and above.

Control plant height in your 4×4 grow tent – Viparspectra PAR 1200w helps you do it with ease:
You don’t want your cannabis plants growing too tall when you’re in the confined space of your 4×4 grow tent. The most helpful tips are maintaining a steady temperature for shorter stems, and knowing when to switch from vegetation to flowering cycle. The Viparspectra PAR1200 has veg/bloom dimming knobs to make the switch easy. You should switch to flowering when your plant is half the desired height, as it’ll continue growing in flowering phase. Cut light exposure from 18 to 12 hours per day to begin flowering.
