SiP noob here, looking for some advice.
I've been trying to run SiP in my nursery "seedling" phase with pretty poor results.
The following stages are close to dialed except the nursery:
-- Room 1: bubble cloner > nursery SiP > veg ebb&flow, then into >>>
-- Room 2: bloom drip dtw
So out of the bubbler I have excellent roots established and 2-4 healthy nodes, then into 1/2gal coco pots for the SiP. I add extra holes to the pots to help the coco to wick up.
Very basic SiP: pots in planter trays under T5HO, watering at pH 5.8 / 0.5-0.7EC consisting of Hydroguard, kelp and fulvic and rooting stimulator such as Rapid Start.
Room 74F / 60-65%RH.
Nursery stage is typically 2 weeks before I can pot up for veg.
Problems are pretty drastic: no new growth, poor root development, significant leaf paling, all within 4-7 days. When I remove from SiP and flush with plain water they bounce back.
I'm convinced the problem is in the root zone as those originally healthy roots take a turn for the worst.
The tray of water never looks too great either and sometimes gathers a slimy film on top. Obvious pathogen or algae or unwanted bacteria. Due to the setup its impractical to cover the SiP from light etc, and I am currently considering scrapping it altogether and running a small E&F or perhaps more bubblers (not ideal as its up on a shelf).
I would like to persevere with SiP if I can get it right.
@Wisher2 originally showed me the way but I've never gotten get his results.
Can't show pics here right now, but what any thoughts from you guys? Is it cover or die? Do you add airstones?
