What You Can Grow With a 250W 4000K MH
Excellent For (Vegetative Growth)
This lamp is a veg specialist:
- Cannabis (veg, mothers, clones) Tight internodes, strong stems, healthy leaf production.
- Leafy greens Lettuce, kale, spinach, arugula, Swiss chard.
- Herbs Basil, cilantro, parsley, mint, oregano, thyme.
- Seedlings & clones Bright but cool enough for sturdy early growth.
- Houseplants & tropicals Philodendron, pothos, monstera, palms, ferns.
Can Grow (but needs bloom support)
It will grow these crops, but fruiting is better with added red spectrum (HPS, CMH 3100K, or LED bloom):
- Tomatoes
- Peppers
- Strawberries
- Cucumbers
- Flowering ornamentals
Not Ideal For
- Full flowering cycles
- Heavy fruiting crops without supplemental red
- Large canopy flowering rooms
MH = veg, not bloom.
