Bloom PRE — Internode Shortener / Stretch Controller

Bloom PRE — Internode Shortener & Stretch Controller

PRE works by shortening the length of internodes on stems and branches — in practice, this crams more flower-growth potential into a smaller, more compact plant. Reduces wasted space on the plant so flowers can develop at more nodes closer together. If you consistently end up with tall, spindly plants that have too much stem and not enough flower, PRE alongside ULTRA can transform your results.

Why growers choose Bloom PRE:

• Shortens internode length — nodes closer together, more flower sites per metre of plant
• Reduces wasted stem growth — energy goes into flower potential, not spindly branches
• Compact, productive plant structure — dense canopy rather than leggy sprawl
• Solves the "tall spindly plant" problem — particularly useful for stretchy sativa genetics
• Pairs with Bloom ULTRA — double-action veg-to-flower transition support (ULTRA reduces stretch, PRE shortens nodes)
• Works in height-limited tents — keeps plants manageable in low-ceiling spaces
• Increases flower site density — more sites means more potential harvest weight

Who it's not for:

For growers in tall-ceiling rooms who want big sprawling plants, PRE is actively working against your goal. Results vary by genetics — already-compact indica strains benefit less than stretchy sativas. Use during transition and early flower; not appropriate once internode-setting is done. Use alongside a full feeding programme as an additive, not a base.
